This patch measures 6cm by 4.5cm and attaches using Velcro, so it fits best on fabrics or clothing that can hold Velcro securely. It may not adhere well to delicate or very thin materials. For best results, attach it to sturdy garments like jackets, backpacks, or hats. If your item can't hold Velcro, consider sewing it on for a more permanent fit.

Yes, the Velcro backing allows you to remove and reposition the patch multiple times without losing adhesion. This makes it ideal for customizing different items or adjusting placement. However, frequent removal on some fabrics might reduce Velcro's grip over time. To maintain durability, keep the Velcro clean and free of lint.

The patch is made from 3D silicon rubber, which is generally hypoallergenic and safe for most skin types. However, if you have a known silicone allergy, you may want to avoid prolonged direct skin contact. The patch is designed primarily as an accessory attached to clothing, minimizing skin exposure.

The Velcro attachment is designed to be removable without leaving adhesive residue or damaging fabric. However, repeated removal and reattachment might cause minor wear on delicate materials over time. For delicate fabrics, consider attaching the patch with sewing to avoid any potential damage.

The silicon rubber construction makes this patch durable and resistant to wear from regular use, including outdoor activities. It maintains its 3D design and color well under typical conditions. To prolong its life, avoid excessive exposure to harsh chemicals or extreme temperatures.
