This patch is designed with a 5cm diameter and uses velcro backing, making it compatible with any accessory or fabric that has a velcro surface. It won’t stick directly to fabrics without velcro. You can easily attach it to jackets, bags, hats, or other velcro-equipped gear. If your item lacks velcro, you might need to sew it on or add a velcro strip first.

The patch uses velcro, which generally does not damage fabrics when removed carefully. However, frequent removal or rough handling might cause some wear on delicate materials. For best results, attach it to sturdy fabrics or accessories designed to handle velcro. Always remove gently to avoid pulling threads or fabric fibers.

The patch is made from 3D rubber material with velcro backing. Rubber is generally safe and non-irritating, but if you have very sensitive skin, avoid prolonged direct contact to prevent any irritation. Since it attaches externally on accessories, skin contact is usually minimal.

You can clean the patch gently with a damp cloth and mild soap if needed. Avoid soaking it or using harsh chemicals, as that could degrade the rubber and velcro. Let it air dry fully before reattaching to keep the velcro adhesive effective and the rubber looking fresh.

With typical use, the 3D rubber and velcro patch should maintain its shape and attachment strength for many months. Over time, velcro may accumulate lint or lose grip, but cleaning it regularly will extend its lifespan. The rubber is durable but avoid excessive bending or harsh conditions to keep it intact.
