Silicone Door Stopper Purchased in August 2025. I bought it without checking the size, and it doesn't fit in my house, so I'm selling it. You can attach the tray to the door and store the stopper. It will be shipped via Yu-Packet Post Mini (subject to change). ↓ From the product page: Made in China Material: TPR Size: 12.4 * 12.4 * 3.5cm (Size may have an error of 0.5-2mm) Color: White Features: Silent operation. It cushions the impact when opening and closing the door, preventing scratches on the wall and reducing noise. (I haven't used it, so I don't know if it actually works as described)
