Adorned with a paw print this handsome key chain is made of 316 stainless steel that is polished to a high gloss. Cremated remains can be placed inside by unscrewing the bail. A rubber o-ring is included on the bail to provide a waterproof seal. We recommend a little super glue on the threads just for extra security. A key chain cremation keepsake is a unique charm or the perfect key fob filled with a small secret that is with you all the time. As a keepsake urn, many families divide their pet’s ashes among different family members and purchase multiple keepsakes. We recommend sealing the compartment closed after placing in the pet’s remains with clear super glue.
