Current Ordering Baseline
MOQ is 100 pieces per design. Paid samples normally take 3–5 days; sample fees are paid separately and never credited. Standard production takes 15–20 days after drawing, material, artwork, packing, and sample approval. Wetop responds to a complete brief within 24 hours.
Different-specification price reference: the acrylic cases hub publishes a compact 150 × 100 × 100 mm, 3 mm magnetic-lid case at 500 pieces from $6 per unit FOB Shenzhen. That general case is not a fitted graded-card slab case quote.
Key Takeaways
- Measure the buyer-supplied slab rather than relying on a brand or grading-format name.
- Approve cavity clearance, removal access, magnet polarity, and opening feel on the paid sample.
- Keep decorative artwork outside the card and grading-label viewing zones.
- Use a production first-off unit to verify the active drawing and sample before bulk release.
- Protect polished faces, corners, magnets, and the buyer product through packout.
The Challenge
A card retailer may need a clear case for a PSA-format slab, but “PSA size” does not release the product. The buyer must approve the actual encapsulated card, label zone, corner geometry, permitted movement, magnet locations, opening method, printed branding, and individual packout.
The case should give the slab visual presence and allow safe removal. A tight pocket can create abrasion or binding, while excessive clearance lets the card move inside the case.
Drawing and Sample Route
Wetop should use an actual buyer-supplied slab or controlled boundary model. The drawing would show outside dimensions, front and rear thickness, slab pocket, safe contact zones, finger or separation access, magnet pockets and polarity, artwork area, polished edges, and carton envelope.
The proposed 5 mm plus 5 mm construction would remain a planning input until the buyer approves weight, edge presence, opening feel, and cost. The physical sample should use production-representative acrylic, magnets, print, and packing.
Sample fees are paid separately and never credited. The buyer should approve fit, movement, opening, magnet alignment, polarity, show surfaces, artwork, film removal, and packout. Any geometry or artwork change would receive a new revision.
Production Control
Production MOQ is 100 pieces per design; this case uses a 500-piece planning release. Standard production planning is 15–20 days after approvals. First-off inspection would verify slab fit, outside dimensions, pocket geometry, magnet position and polarity, artwork revision, edge finish, and individual packout.
Every show face would receive cosmetic inspection. Magnet and fit checks should use an approved fixture or actual slab sample. Unit and carton labels would connect the production lot to the active drawing and artwork.
Acceptance Targets
- Buyer-supplied PSA slab seats without forced insertion.
- Approved movement and visible margin remain consistent.
- Magnets align with correct polarity and buyer-approved opening feel.
- UV artwork matches proof, location, and viewing side.
- Polished show edges meet the signed boundary sample.
- Packing protects clear faces and keeps magnets away from loose metal items.
Commercial Plan
The quote would separate acrylic, machining, magnets, UV printing, proof and sample, inspection, individual presentation pack, master carton, and freight. Any alternate thickness or box would be returned as a separate revision rather than a silent substitution.

Quote and Approval Sequence
A useful quote starts with a controlled brief rather than a family description. Send actual slab samples, maximum envelope, label viewing zone, case thickness, cavity clearance, removal method, magnet grade and orientation, opening feel, artwork, quantity, and packing. Wetop can then return a drawing review, per-version quantity table, manufacturing notes, sampling route, packout assumptions, and the commercial fields that still need buyer approval.
The paid sample is the physical decision point. It should confirm slab insertion and removal, clearance, magnet seating and polarity, opening feel, corner and edge finish, artwork position, label visibility, and protection without pressure on the slab. Sample fees are paid separately and never credited. Approval should identify the sample date or reference, active drawing revision, accepted deviations, and any buyer-controlled test conditions.
Production release follows only after the drawing, material, artwork, sample, quantity allocation, packing, price, and payment terms are approved in writing. A first-off inspection checks the production setup against that release. If the first-off exposes a mismatch, the affected operation is corrected before the lot continues.
Packout is part of the released product. This plan calls for film or interleaf on polished surfaces, restrained case halves, magnet-safe handling, corner protection, SKU labels, and cartons sized to prevent dense cases from shifting. The written quote should distinguish included factory packing from buyer-side retail packing, labeling, consolidation, or freight services.
Planning Outcome
This page is a Manufacturing Case: a realistic production model based on Wetop's current fabrication, printing, assembly, inspection, and export-packing capabilities. It is not presented as a named buyer shipment, testimonial, field-performance result, or automatic compliance outcome.
The useful outcome is a release package that procurement can review: one active drawing, one approved sample reference, a version and quantity table, clear acceptance checks, a packout specification, and a written commercial offer. That package makes supplier comparison more specific and reduces avoidable interpretation between sample and production.
For a similar project, compare the quote against the same released scope. A lower figure is not comparable if it excludes artwork setup, hardware, assembly, inspection, protective packing, or a material grade that the approved sample requires.

Buyer Release Checklist
Before approving production, procurement should be able to point to one current file for every decision. The release folder should contain the signed drawing, approved artwork proof, material and finish selection, sample reference, quantity by physical design and artwork version, acceptance notes, packing specification, carton labels, destination, Incoterm, and requested shipment timing. Verbal approvals and image-only chat messages should be transferred into that controlled record.
The buyer should also mark responsibility boundaries. Wetop controls the acrylic fabrication, agreed printing or assembly, inspection, and factory packout shown on the quote. The buyer controls the supplied product model, final artwork content, destination requirements, local installation, end-use review, and any regulatory or third-party test criteria not expressly included in the written offer. Naming those boundaries early prevents a capability statement from being mistaken for a product certification or site approval.
When a change arrives after sample approval, identify whether it affects geometry, material, finish, hardware, artwork, packing, quantity allocation, or timing. Wetop can price and schedule the changed scope after receiving the revised file. The earlier approval remains the reference for unchanged fields, but it does not authorize an unreviewed revision. This is also the point to update the first-off inspection sheet and carton labels before production continues.
Common Questions
Can production start from a photo or rough sketch?
A photo or sketch is enough for an initial feasibility discussion, but production needs a released drawing. Wetop can turn the brief into a drawing for approval. Buyer-controlled interfaces still require dimensions, physical samples, or controlled models before the paid sample is released.
Does the 3–5 day sample timing include every approval?
No. The 3–5 day baseline starts after the sample scope, drawing, material, artwork, price, and payment are confirmed. Buyer review, courier transit, revised files, special material procurement, and repeat sampling are separate from the factory sample window.
Can the production order be split across versions or destinations?
Yes, when each physical design meets the 100-piece MOQ and the allocation is approved before release. The quote should list quantities by physical revision, artwork version, carton label, and destination. Small splits can add proofing, labeling, packing, and handling cost even when the total quantity is large.
Planning a similar custom acrylic program?
Send the drawing, quantity by version, product samples or models, artwork, packing requirement, destination, and target timing. We will return the open questions and a written manufacturing quote.
