I've made a holder for pet registration tags and rabies vaccination tags using cowhide leather. It's a gentle, milky white color and the leather is firm and structured. Once you put the tags inside, you can wrap it around the collar and secure it with a spring snap, so it won't dangle. I've used a 15mm spring snap to make it difficult to come undone. I will engrave your pet's name above the snap ★ Choose from Gothic uppercase, lowercase, or small lowercase letters (*^^*) ■ Engrave your phone number on the back for an additional 50 yen. If you'd like this, please let me know before you purchase. Size: Height: 3.5cm Width: 4cm Thickness: 1.5cm Compatible tag size: [approx. 2.5cm tall x 3cm wide] Compatible leash width: [approx. 2.5cm] * We offer a discount of 100 yen off the second item and onwards when you purchase multiple items(^^) 3 items purchased = -¥200★ * Items made to order based on requests are not eligible for the discount. * I do not offer holds.
