Xinrui's product information confirms that samples are available, but it does not set a required number for checking shape or material consistency. Ask the supplier how many pieces can be provided, then request enough of the intended specification to compare them with one another and with an approved reference sample.
Before evaluation, agree on what you will inspect and how differences will be judged. The listing does not provide a formal sampling plan, inspection procedure, or acceptable variation, so these criteria should be confirmed directly with the supplier.
The non-adhesive nipple covers are described as made from 100% solid silicone. They are listed in 8 cm and 10 cm sizes, with nude, khaki, brown, and coco color options. Specify the size and color you plan to order when requesting samples; confirm whether the sample set should contain one option or several.
Compare the shape and material across the delivered pieces, using the agreed product specification and an approved sample as your reference. The stated care instruction is hand washing. No wash-cycle test is defined, so clarify with the supplier whether care-related checks are relevant to your evaluation.
| Item | Listed information | Confirm with the supplier |
|---|---|---|
| Samples | Available | How many pieces can be supplied for evaluation |
| Material | 100% solid silicone | Criteria for comparing material consistency |
| Sizes | 8 cm and 10 cm | Which size or sizes to include |
| Colors | Nude, khaki, brown, and coco | Whether to assess one color or multiple colors |
| Care | Hand wash only | Whether care-related checks are part of the evaluation |
| Packaging | OPP bag or custom packaging | Which packaging option is required |
Request multiple pieces in the intended size and color, and agree in advance on the sample quantity and comparison criteria. Keep one approved piece as a reference for reviewing later production. This makes the evaluation specific to your order without assuming a test method or tolerance that the product information does not state.
Xinrui's company information mentions raw-material, in-process, and finished-goods inspections. It does not say that these inspections establish a particular sample count or product-specific acceptance standard for this non-adhesive model.
No fixed quantity is provided. Confirm availability with Xinrui and request enough pieces to assess the consistency you need.
Identify the size and color you intend to purchase. The listed choices are 8 cm or 10 cm and nude, khaki, brown, or coco. You can also confirm whether you need an OPP bag or custom packaging.
The supplied product information gives material, size, color, packaging, and care details, but no formal inspection method or acceptable variation. Agree on those points with the supplier before evaluating samples.
Dongguan Xinrui Underwear Co., Ltd. describes itself as a factory-based supplier of women's invisible underwear and intimate apparel, with product development, mass production, OEM/ODM, and packaging customization services. Its profile lists 2007 as its establishment year and a factory area of 10,000 sqm. ISO 9001 and BSCI are among its stated certifications.
The company also describes a long-term supply relationship with a US online apparel seller involving repeat orders of invisible nipple covers. This case concerns its broader product supply; it does not specify a sample quantity or inspection protocol for the non-adhesive silicone model. Daily wear and bridal wear are listed as use scenarios for the broader invisible intimate apparel range, not as product-specific test conditions for this cover.
For technical questions, contact judy@xinruibra.com.
Because no sample count or formal consistency standard is published, confirm both with the supplier before ordering. Request samples that match your intended size and color, agree on the comparison criteria, and retain an approved piece as the reference for any later production review.
