Made with nylon paracord from Europe and America. You can change the colors of the cord, beads, and hardware at no extra charge. The collar is about 4cm wide and 1.3cm thick, making it a sturdy collar. The price is for a half-choke type up to 35cm. For every 10cm over that, it's an additional 500 yen. You can also change to an adjustable belt type for an additional 800 yen. *You can choose the belt color from the available stock. We offer a discount if you order a leash and collar set. The leash will be made using the same colors. Please comment if you'd like a set. You can see other designs at #asowan_works☆ Thank you for looking!
