Nothing seems to be more important to good pet owners than their pets' health and wellness, which is why we have created our Silicone Pet Tags! Available in 3 colors with the choice of a paw-shaped or a smaller round tag, pets can experience many of the same benefits as their owners from wearing EFX technology! All EFX Silicone Pet Tags are made of the highest quality, non-toxic, medical grade silicone and come equipped with a metal O-ring for easy placement on your pet's collar. Why should humans be the only ones who get to benefit from our products? Let your pets experience the effects of EFX too!
