O-340 Ashi Pita Cap M Size, Sliding Type Purchased last summer from Dinos online shopping with the intention of using them. The product cost 3,300 yen. I tried them out, but the shape (size) didn't fit, so I couldn't use them and have been storing them at home. Therefore, one has been opened, and I tried to attach only one, but gave up, so they are in almost unused condition. Three sets are unopened and unused. The following is quoted from the online shopping page: Please consider. ● The bottom surface is made of high-density polyethylene for good sliding, allowing for smooth furniture movement. ● Easy to install with stretchable silicone caps. ● Can be used on flooring and carpets. ● Compatible leg sizes: Round diameter 26 to 34mm, Square side 22 to 30mm 【How to use】 (1) Check if the size and shape of the legs to be attached match the compatible size and shape of the leg caps, and place them on top of the legs to be attached. (2) Turn the cap completely inside out. (3) Align the bottom of the cap with the bottom of the leg to be attached, and stretch the silicone part to cover the leg. ■ Size: Width 3 x Depth 3 x Height 3cm (per piece) ■ Set of 16 (for 4 legs) ■ Materials: Silicone resin, nylon 66, high-density polyethylene ■ Made in China or Japan ※ This product does not prevent scratches on the floor. ※ Do not push or pull the chair while seated or with foreign objects on the floor.
