Pink and black carabiner, perfect for climbing and outdoor activities. - Color: Pink and black design - Material: Metal and nylon - Size: Approximately 10cm Thank you for looking. This is a plastic bottle holder I received at a live concert at Zepp. For standing concerts, you can attach this to your belt loop and go hands-free! Insert the cap of the plastic bottle into the black rubber ring. It is unused. I brought it home without using it. I will send it via Mercari delivery.
