These tags are made of RIGID TRAFFOLYTE - a hard, acrylic plastic, similar to Formica. Many kitchen worktops are made of Formica, so you are probably familiar with this material.
Note that plastic can crack and break. Dogs, particularly, will tug hard if their tag catches on something, so we do not generally recommend these tags for use as permanent Pet Tags. A metal tag is far superior and we have many beautiful colours in the Anodised Aluminium ranges. Also, Plastic Tags used as pet tags are generally NOT covered by our guarantees.
We have NINE options available. The tags are 25mm or 30mm in diameter and 1.7mm thick.
