Please note the patch back style：
Iron-on backing: This type is not permanent, it can only be temporary. If you want permanent solid hot melt adhesives you not only need to use thread stitching. Typically, this type of patch is typically used in places where it is not often washed, such as bags, boxes, and the like. Because they are not always washed, the hot melt is basically guaranteed to be permanent. It is very simple to use and can be ironed to 160-220 degrees for about 10 seconds. The hot melt adhesive can stick to it.

Velcro backing: It is characterized by durability, easy pull, easy closure, washable, color and variety. The principle refers to two rows of woven nylon, which is a row of numerous hooks, and the other row is a small round hole, which can be firmly stuck when the two rows are stacked together.
