Unused Water Bottle Bottom Cover, Silicone, Set of 1 with Double-Sided Tape. I purchased this item a few days ago, but it doesn't fit my water bottle, so I'm selling it. I tried to attach it to see if it would fit, but I couldn't, so it's listed as unused. Please note that the bag has been opened once. The actual item is shown in the 5th photo. Photos 1 through 4 are product descriptions. The water bottle is not included. ◆ Size: Diameter approx. 7cm ◆ Color: Blue, 1 piece [Product description from the purchase site below] ⭐︎Only one silicone bottom, water bottle cover not included. ⭐︎[Protection and Reinforcement] Prevents the bottom of the water bottle cover from fraying or becoming worn out. It can protect and reuse covers with torn bottoms. ⭐︎[Applicable Range] Applicable to water bottle covers with a diameter of 7cm and a capacity of 0.35L to 0.6L. Water bottles and plastic bottles with a bottom diameter of 7cm can be used directly. [Tape Included] If you feel it might slip off easily, you can reinforce the non-slip feature with the included double-sided tape. The tape is not for attaching the silicone bottom. ⭐︎[Washable] Made of silicone, it can be removed and is easy to wash. *Please check the size before purchasing. It will be folded and shipped via Yu-Packet Post Mini, so please understand this in advance. #WaterBottleCover
