The direct answer is to specify the product as an IML-printed TPU case with a detachable ring stand, then control artwork ownership, phone fit, print proof, ring function and packaging before production. The IP Case published specification is 58 × 4.5 mm for the stand, 24 g, iPhone 15–18 series, 360° rotation, replaceable rubber strap, magnetic holder and detachable ring holder.
A custom character phone case combines licensed or owned artwork, a phone-specific TPU body, an in-mould-label print, a ring-holder structure and retail packaging. Those parts need to be approved as one repeatable product, not as five unrelated samples.
1. Confirm the artwork right before the design
IML printing does not create ownership of a character. Before the factory starts proofing, the buyer should confirm that it owns the artwork or has permission to use it in the intended markets and sales channels. Supply the artwork as a vector file where possible, with a colour reference and a written description of which elements may not be changed. If the artwork was supplied by a licensor, the approved style guide and approval route should also be recorded.
2. Build the print proof around the actual phone model
A flat image does not show how artwork will follow the case edges, camera opening or ring position. The proof should show the print on the selected phone model, with image scale, crop, background, transparent areas, colour expectations and the safe area around the ring. Approve the digital proof first, then approve the colour and print result on a physical sample under an agreed light source.
The exact phone model must be part of the order. The IP Case is published for iPhone 15–18 series, but each body still needs phone-specific fit confirmation. A pattern proof does not prove cut-outs, button access, camera clearance or case fit.
3. Separate the case, print and ring-holder checks
Treat the product as three linked approval areas. First check the TPU body and phone fit. Second check the IML print and surface. Third check the detachable ring stand: magnet position, 360° rotation, replaceable rubber strap and the action of attaching and detaching it. Record each item with photos, a measured sample and a pass/fail result.
The product route also changes how you describe it to customers. Review the difference between an integrated case and a separate holder in the <a href="../blog/phone-case-with-ring-vs-separate-ring-holder">phone case with ring guide</a>. The <a href="../products/ipcase">IP Case product page</a> gives the current published product specification.
4. Approve colour, logo and packaging as separate variables
Character artwork needs a sealed colour reference because file colours and final print can look different. Confirm the print method, background, edge treatment and any logo used by the brand. Packaging needs its own proof: retail box or card, artwork, barcode, labels, quantity per carton and shipping marks.
The <a href="../blog/custom-logo-phone-holder-methods">custom logo guide</a> explains artwork files and proofing, while the <a href="../blog/custom-packaging-for-phone-accessories">packaging guide</a> lists the retail-pack information to fix before production.
5. Freeze the approved version
Keep one golden sample and a signed approval record containing the phone model, artwork revision, print proof, colour reference, ring function, packaging proof and inspection result. Any later change to the character, phone body, ring, colour or packaging should receive a new version and, where it affects form, fit or function, a new sample approval.
Ready-molded models start at MOQ 50 pcs per model. Sampling takes 7–10 working days after requirements and artwork are confirmed. Production takes 7–12 days after sample approval, followed by 3–5 days for packing and final inspection, FOB Shenzhen. Send the phone model, authorised artwork, target quantity, market and packaging requirement with the sample request.

Frequently asked questions
Can the factory use any character image?
No. The buyer must own the artwork or provide documented permission for the intended market and sales channel. IML printing does not transfer or create ownership of a character.
Is IP Case a custom phone case or a ready-molded model?
It is a ready-molded platform that can be customised with authorised artwork, logo, colour and packaging. The published stand specification is 58 × 4.5 mm and 24 g for iPhone 15–18 series.
What files should a buyer send before sampling?
Send the exact phone model, vector or high-resolution authorised artwork, colour reference, quantity, target market, logo instruction and packaging requirement. The digital proof should include crop, scale, transparent areas and ring-position clearance.
What should be checked on the physical sample?
Check phone fit and openings, IML print and colour against the sealed reference, 360° rotation, the replaceable rubber strap, attachment and removal of the detachable ring, logo, retail packaging and the signed golden sample.
What are the MOQ and lead times?
Ready-molded models start at 50 pcs per model. Samples take 7–10 working days after artwork and requirements are confirmed; production takes 7–12 days after sample approval, followed by 3–5 days for packing and final inspection, FOB Shenzhen.
