• Not ABS/PC hard-shell luggage: our focus is sewn or wrapped structured construction with panels, foam, magnets, hardware and fitted interiors.

These products sit between conventional bags and rigid hard-shell cases. The exterior can be sewn or wrapped, while paperboard, MDF, honeycomb board, plastic sheet or another selected support controls shape, protection and folding behavior. We evaluate the complete structure for repeatable production before bulk manufacturing.

Structured case and storage-box categories

Leather jewellery boxes, watch boxes and gift boxes

Leather-wrapped hard boxes use the same board, wrap and fitted-interior construction. DINLEEY develops leather and leatherette jewellery boxes, travel jewellery cases, watch boxes, ring, pendant and cufflink boxes, and presentation or gift boxes with magnetic closure — for jewellery and watch brands, gifting programmes and packaging ranges.

A brief might add a travel case to a home jewellery box range, resize a faux leather jewellery organiser, or develop a leather-look presentation box for the gifting season. Each goes from custom brief to development and sampling, with production after sample approval. Share dimensions or a reference box; bags and small leather goods are on Functional Bags & Leather Goods.

Why the internal structure matters

The outer material does not determine the result by itself. Board type and thickness, hinge lines, folding direction, seam or wrapping allowance, edge treatment, base support and closure position work together. A structure that looks correct when empty may behave differently after loading, repeated folding, storage or transport.

• Shape retention: the box or case must hold the intended geometry without unnecessary weight or bulk.
• Folding behavior: flexible joints, removable panels or magnetic connections must close and reopen in a controlled sequence.
• Surface finish: wrapping, stitching, binding, edge control and hardware alignment affect the finished appearance.
• Load distribution: handles, bases, dividers and closures must be connected to the supporting structure rather than only the surface material.
• Production repeatability: board cutting, lamination, wrapping, sewing and assembly tolerances must remain practical for repeat orders.

Materials and construction options

Depending on the approved specification, a case may use PVC synthetic leather, microfiber leather, selected genuine leather, woven textile, suede-like lining, nonwoven lining, foam, paperboard, MDF, honeycomb board, PP or other plastic sheet, magnets, hook-and-loop materials, zippers, hinges, metal hardware and custom interior fittings.

Material selection is based on the required appearance, folding frequency, load, moisture exposure, cleanability, odor expectation, shipping method, available quantity and target cost. MDF can provide stiffness and weight; honeycomb or plastic boards may be considered when lower weight or moisture behavior is more important.

From concept to production-ready structured product

Structured cases and storage boxes FAQ

What is a structured case?

A structured case combines a sewn or wrapped outer surface with boards, foam, inserts or other supporting elements that control shape and protection.

Can DINLEEY develop a collapsible rigid storage box?

Yes. Folding panels, removable supports, magnetic connections, dividers and closures can be developed around the required assembled shape and storage volume.

Do you only make genuine-leather cases?

No. Construction may use selected genuine leather, PVC synthetic leather, microfiber leather, textiles or combined materials according to appearance, performance and target cost.

Is this the same as ABS or PC hard-shell luggage?

Our main focus is sewn or wrapped structured construction using boards, foam, panels, closures, hardware and fitted interiors. Hard-shell requirements are reviewed according to the complete product specification.

Do you develop leather jewellery boxes, watch boxes and gift boxes?

Yes. Jewellery boxes, travel jewellery cases, watch boxes, ring, pendant and cufflink boxes, and leatherette presentation or magnetic-closure gift boxes are developed as structured cases — board, wrap and fitted interior — from brief to sample, with production after sample approval.

How are order quantities for custom cases set?

Quantities are reviewed per project, based on structure, materials and customisation, and confirmed in our quotation.

How long does sampling take?

Standard samples typically take 7–15 days once the specification is confirmed; special customization such as moulds or special materials is scheduled separately. Bulk production timing is confirmed with the quotation.

Can you add our logo and produce under our brand?

Yes. As an OEM/ODM manufacturer we produce under your brand, never our own. Logo options include embossing, debossing, printing, embroidery, metal plates and woven labels.

Should we choose a foldable, semi-rigid or fixed hard case?

If the case must protect its contents but also store or ship flat, a foldable sewn structured case is often the best fit: board-reinforced panels give shape, and the case folds down when empty. We help you choose between foldable, semi-rigid and fixed structures before sampling.

What is an EVA case, and do you make EVA cases?

An EVA case pairs a semi-rigid moulded EVA shell with a fabric or leatherette cover, zip and lining. The shell is moulded by our partner supply chain; the sewing, lining and assembly are done by us on our own production line.

Can you make a custom foam insert or fitted interior for our product?

Yes. Interiors are built around your actual product with cut foam, padded dividers, elastic loops, mesh pockets or removable trays. Send the item or its dimensions and we fit the sample to it.

What do we need to send for a quote, and can we start without drawings?

A sketch, a reference photo or the product itself is enough to start. Add rough dimensions, contents, preferred materials and your quantity range, and we turn it into a sample specification.

Are you a factory or a trading company?

DINLEEY is an OEM/ODM manufacturer with its own production line, not a trading company and not a brand. Cutting, sewing, lining and assembly are done in-house.

Will you sign an NDA and keep our design confidential?

Yes. We can sign an NDA before you share drawings or samples, and your designs are produced only for your brand.

How do you keep bulk production consistent with the approved sample?

Bulk is inspected against the approved sample, plus basic testing. On request, we can help arrange test reports from professional third-party labs for each order.

Which factory in China makes custom leather jewelry boxes, watch boxes and hard cases for brands?

DINLEEY, an OEM/ODM manufacturer in Guangzhou, China, develops and produces jewelry boxes, watch boxes, gift boxes, hard cases and collapsible storage boxes for brands on its own production line. Products are made under your brand; DINLEEY does not sell products under its own brand.

Can you develop a box or case from our sample, photos or drawings?

Yes. A physical sample, reference photos or drawings are enough to start. We confirm size, structure, cover material and interior, then make a sample for your approval; standard samples take 7–15 days without special customization.

Can you make vegan-leather jewelry boxes and watch boxes?

Yes. Vegan-leather versions use PVC synthetic leather or microfiber leather wrapped over boards, with velvet-like or suede-like linings. Send the target colour and finish, or a swatch, and it is confirmed on the sample.

Can one factory make the case together with its insert, tray and pouch?

Yes. The outer case, foam or fitted insert, trays, dividers and soft pouches are developed together in one project and checked together on the sample, so the parts also fit each other in bulk production.

Can you make custom fabric-covered hard makeup cases, vanity cases and storage boxes?

Yes. We wrap a rigid board shell in fabric, microfibre leather or PVC synthetic leather and build the interior around your range: cantilever or lift-out trays and fixed or removable dividers. Sizes are developed for your products rather than picked from a catalogue, and every case is made on our own production line. Send dimensions, reference photos or a sample; a first sample usually takes 7–15 days.
