[Single Count] Custom, Cool & Awesome {3" Inches} Small Round US Armed Forces K9 Tactical Tracker Unit Wolf Bear Paw Print (Swat Type) Velcro Patch &ldquo;Green & Black&rdquo; THE QUALITY: This patches materials are sourced from only the very best manufacturers and are made in Japan and stored in the United States. THIS IS GREAT FOR: Hats, binders, jackets, backpacks, vests and MORE! WHAT MATERIALS WILL VELCRO STICK TO: Velcro patches will generally stick to wool, loose-looped felt, looped nylon fabrics, fleece, some microfiber fabrics, velvet, some knit fabrics. Velcro doesn't stick to all fabrics. The fabric must have a series of small loops on its surface or offer a pile that the hook-side of Velcro tapes or products can grab onto. The hooks must be able to sink into the fabric deeply enough, and the fabric's fibers must have something the Velcro can clutch. WARNING: Use caution when sticking hook-sided Velcro to some fabrics; because excessive attaching and detaching the Velcro can make the fabric develop a fuzzy appearance or separate the fibers a bit.
