The available product information does not define a standard warranty period or guaranteed adhesive lifespan for this full-cup matt nipple cover. It confirms a 100% silicone construction and provides details about sizes, colors, packaging, and samples, but no formal warranty terms are included. Buyers should obtain written confirmation from the supplier before placing an order.
A warranty period and adhesive service life are different matters. A warranty usually defines the supplier’s responsibility for defects or specified failures, while adhesive life refers to how long the product may remain reusable or maintain its grip under stated conditions. The supplied record does not provide either duration.
The information also does not explicitly classify the material as medical-grade silicone. It only identifies the fabric type as 100% silicone. Therefore, buyers should request documentation if medical-grade status is an important purchasing requirement.
Dongguan Xinrui Underwear Co., Ltd. describes an X3 upgraded adhesive technology for its nipple cover products. The stated objectives include improved adhesion stability, a secure fit, skin-friendly comfort, and the ability to regain stickiness after washing. These are general technology claims and should not be interpreted as a quantified adhesive-life promise or a warranty for this specific matt nipple cover.
The company also reports inspections covering incoming materials, manufacturing processes, and completed products. Its profile lists certifications such as ISO 9001 and ISO 10993, but the supplied information does not indicate that these certifications establish a warranty period or adhesive guarantee for this item.
A customer case involving a US online apparel seller refers to repeat purchases and comments on strong adhesion and waterproof performance. However, the review does not state a warranty term or measured reuse period and cannot confirm either specification.

The product record gives no specific adhesive-life estimate. General company statements discuss adhesive stability and possible recovery after washing, but they do not establish a guaranteed lifespan for this model.
That is not expressly confirmed. The specification states 100% silicone, but it does not describe the material as medical-grade silicone.
Request the warranty duration, covered defects, expected adhesive performance, washing and reuse conditions, storage requirements, and any limitations related to skin contact or application.
