Hand-dyed and hand-sewn "I was troubled by the clinking sound of the bill barking, so as a leather craftsman, I made a sturdy and lightweight dog tag holder for my dog." Instead of hanging the metal license tag or rabies tag as is, you can keep it in your pocket to reduce noise and shaking. Because it is something you wear all the time, we prioritized ensuring your dog's comfort during the production. Suitable for dogs from small to extra-large breeds, regardless of breed or coat. This lightweight, thin genuine leather license holder can be attached directly to the collar, compatible with collars up to 2cm wide. For harness enthusiasts, insert the dog hook from the Nascan side of the leash (if the belt passes 2 centimeters). - Material: Genuine leather - Color: Light green - Manufacturing method: Hand sewing, hand dyeing - Compatible collar width: up to 2cm Height 3.5 cm, Width 4.0 cm, Light and durable - Attachment: Insert into the collar by threading the belt *My dog has worn a license holder for many years, but the hook has never been opened. Even if the hook is undone, it fits securely and won't easily pop out—this is the excellent stretch of natural leather.
