Worry Tags are a cross between a dog tag and a worry stone. There are two sizes: full size and mini. The full size is 2" by 1 1/8", the mini is 1 1/2" by 7/8". The front has various images while the back has either checkered or pin-striped texture. They come in Zirc, Titanium, Copper, Brass, or Bronze. Stainless steel will be introduced soon. Weight will vary by thickness and material.
