I purchased this item on Rakuten for 1880 yen, but I accidentally bought the wrong size. This is a set of 16 quiet and smooth chair leg caps for L-sized chair and table legs (suitable for 27-32mm). They are furniture sliders that glide smoothly and have a soundproofing effect. They are fluorine-coated, making them resistant to dust. They are washable and easy to care for. Please remove the styrofoam before use. ★ Important Notes 1. Before use, be sure to thoroughly remove dust and oil from the contact surfaces of the chair legs and chair leg covers. If dust or dirt gets trapped between the chair leg caps and the floor, it may scratch the floor, so clean frequently and take care to remove any debris. Also, if the chair legs are thin, make sure to attach the caps securely. 2. Depending on the chair legs and the material, the caps may come off easily. Please check beforehand. Oil on the chair leg covers can cause deterioration, so when cleaning, wipe gently with a mild detergent and air dry without wiping off the surface moisture. 3. Do not place near fire. For chair leg scratch prevention and to prevent deformation, store away from direct sunlight and high temperatures and humidity. Keep out of reach of infants and young children to prevent them from licking or putting the chair leg caps in their mouths, and handle with care. 4. You may see streaks (weld lines) on the surface of this product, but this does not affect the quality, so please use with confidence. I purchased this item new, but the size was incorrect. Although it is a new, unused item, please understand that it has been stored at home. I have carefully inspected the item, but there may be oversights as I am not a professional. Thank you for your understanding.
