Products We Supply
- Tempered Glass
- Match finished glass protectors to the exact device family and model, then compare HD clear or privacy options where listed. The collection separates Apple phones, Samsung phones, iPad Air and Nintendo Switch; the available finish varies by family. Open the relevant product page to review that range.
- Cutting Films
- Compare the film material and finish before choosing an item for your cutting workflow. The collection includes TPU, EPU, PVC, TPH, PET and UV families, with individual thickness and sheet formats stated on the relevant product pages. Review the proposed film together with your machine, device models and cut-file needs.
- Cutting & Curing Equipment
- Distinguish film cutting from UV curing and combined installation workflows. The machine collection includes dedicated cutters, curing equipment and selected combined-function entries. Use the individual machine pages to compare the stated functions, working format and material requirements; discuss a demonstration or equipment quotation separately from film samples for your setup.

Working With JJT
Questions About JJT Before Starting a Project
What Can I Source?
Start with a finished protector for a specified device, cutting film for an on-demand workflow, or a cutting machine. Share the target models and intended sales channel so the discussion can focus on the right product, fit and packaging.
How Should I Review Factory Evidence?
Company figures describe JJT’s stated operations. Use the factory tour to see the working environment, then ask the team how the relevant process applies to your chosen product. A certificate or test report applies to its stated scope; it does not establish the performance of every product. Review our certificate library and request the latest documents relevant to the material, model and market you plan to order, and evaluate samples against your requirements.
What Should I Send for a Quote?
Send the device or film size, material and finish, quantity, packaging or logo requirements, destination and target timing. Ask JJT to confirm the applicable MOQ, sample options, lead time and quotation for that specification.
