Made of silicone material, it can be attached to collars, harnesses, bags, etc.! It glows, so you can rest assured even when walking your dog at night. Batteries are included from the start, and it's a product that can be used again by replacing the batteries when they run out. This is a pendant light purchased at the Wiggle Wiggle Myeongdong store in Korea in October 2025. I don't have many opportunities to use it, so I'm selling it. ^_^ ◆Size◆ Length 8.7 x Width 4.2 x Thickness 1cm Korea Dog Pet Pet goods Smile Smile flower LED Light LED pendant for walks #Halloween on Mercari
