What this product is

Hinged retainer cases come off a China line as small storage boxes, and the buyer is sourcing the case itself, not an aligner and not a dental service. The case is presented as storage, and this page does not complete a medical device registration. Where a market regulates retainer cases, that work is extra and is not inside the unit price. Cavity size, hinge style, vent holes, and color are the estimated factors behind the quote. A typical first order can private-label a pad print and pick a stock color on an open mold, while a new cavity length needs tooling. The brief should state inner length, hinge type, vent yes or no, color, and print position. The figures in view are indicative ex-works pricing before freight. An approximate shipped cost varies with hinge quality and with whether a foam insert is added. Potential cracking at the hinge after repeated opening is a sample test the buyer can run on the approved color and the case together.

Why it is interesting

Hinge quality and cavity length are the two checks that matter on a small case.
A storage-only brief keeps the case apart from aligner supply.

What to specify

Role: Storage only
Vent: Optional holes
Insert: Foam only if briefed

Customization and private label

Pad print and a stock color are first-order changes, while a longer cavity needs tooling.

Some customization is realistic on this kind of product. Private label packaging is often possible once artwork is approved. Read how private label manufacturing in China is handled, and when a new product needs the OEM/ODM path.

How the desk would source it

Note 1. Measure inner length against the retainer you intend to store, and state it in millimetres.
Note 2. If a market regulates the case, budget that file outside the unit price.

The usual path is the same as other China factory sourcing: confirm the spec, compare factories, sample, then inspect before shipment. China supplier verification and China quality inspection are available. Goods can be received at the Xiamen warehouse and moved through China warehouse consolidation or sea, air, and express freight.
