The Stainless Steel version is either 30mm or 34mm in Diameter and 3mm thick, making them really nice and heavy duty.

The Brass version is 34mm and 2mm thick so again nice and heavy duty.

The Charm can be fitted to both or bought separately.

The engraving is deep and permanent, not just marked like most, as such we can offer a readable guarantee that lasts as long as your pets is with you.
