AniFuns to bring fun, humor, and a touch of comedy to your best friend! Have fun finding the model that suits them perfectly! Is your best friend a dog, a cat, a goat, a horse, a unicorn, a T-rex? The Velcro is so light that it won't bother them. This model is one-sided and can be attached and Velcroed onto a leash, harness, or collar. The back of the design is gripped (easy to install on tactical harnesses) but also has the velvet side for installation on any support (which you can sew onto your harness, a jacket, a backpack, etc.). This Velcro measures 12.5 cm x 5 cm, and is also water and UV resistant.
