Written sample approval helps ensure the adhesive bras delivered in production match the product you evaluated. Your notes should identify the sample, confirm its specifications, describe the fit and adhesion review, and state the agreed packaging and customization details. For Xinrui’s V-shaped invisible sticky bra pads, the approved sample can also serve as the reference for the production order.
Begin by recording the product name and design so there is no confusion about which item has been approved. The sample described here is a V-shaped invisible sticky bra insert with a full-cup design. Its listed size is 11 cm by 11 cm, and the stated fabric composition is 95% cotton and 5% silicone. The available colors are nude and black, and the care instruction is hand wash only.
Include the selected color and verify the size and composition against the submitted sample and order specification. Write down the approval date as well, and identify the approved item as the production reference.
Evaluate the pads in the context in which they will be worn, such as with the intended backless dress. Your approval record can describe observed fit, coverage, visibility beneath the garment, and adhesion during the agreed assessment.
The available product information does not set a numerical adhesive-strength score, wear-time target, or reuse-cycle requirement. If any of these are important to your order, agree on the test method and acceptance threshold with the supplier before signing off. Do not substitute an assumed performance figure for a criterion the supplier has not confirmed.
Xinrui lists OPP bags and custom packaging as options. State which packaging you have selected, and document any requested logo, design, or other customization separately from the product specifications. Samples are available, and the listed custom minimum order quantity is 10 pairs.
Keeping these commercial details in the approval record makes it easier to compare the final order with the approved sample and prevents packaging or customization choices from being left implicit.

| Product identity | V-shaped invisible sticky bra insert with full-cup design | Product name and shape; state that the approved sample is the production reference |
| Size and composition | 11 cm by 11 cm; 95% cotton and 5% silicone | Confirm the dimensions and material composition against the sample and order details |
| Color and care | Nude or black; hand wash only | Specify the chosen color and carry the care instruction into product documentation |

For clear production follow-up, label the approved sample with its product name, color, size, and approval date. Keep the written notes with the order documents and make clear that production should be checked against this sample and the recorded specifications.
Xinrui reports incoming raw-material inspection, in-process production inspection, and finished-goods inspection. Its stated credentials include BSCI, RoHS, REACH, ISO 9001, BRC, and ISO 10993. A reported US-based online apparel seller has used its invisible cover products for everyday and formalwear assortments, including bridal and backless-dress applications, with recurring orders and customer feedback on fit and adhesion. The case does not provide a sample-approval test protocol, so buyers should define their own evaluation criteria with the supplier.
Note the V-shaped full-cup design, 11 cm by 11 cm dimensions, 95% cotton and 5% silicone composition, selected color, and hand-wash-only care instruction.
State the intended wear context and record observed fit, coverage, visibility, and adhesion. Since no numerical adhesion or wear-time standard is provided, agree on any required test and threshold before approving the sample.
Choose OPP or custom packaging, list any customization, and confirm that the approved sample will be used as the production reference. Xinrui indicates that samples are available and gives a custom MOQ of 10 pairs.
Make approval actionable by documenting the sample’s design, dimensions, material, color, care requirements, intended-use evaluation, packaging, and agreed custom features. Keep any adhesion-performance requirements explicit and mutually agreed, since the product information does not provide numerical criteria.
