These are wooden legs for the Muji (Mujirushi Ryohin) leg-attached mattress and bed frame. - Material: Wood - Size: 20cm - Screw size: M8 - Quantity: 4 - Shape: Cylindrical - Color: Natural I realized they were the wrong size after attaching them, so I only used them for one day while waiting for the new ones to arrive. Felt stickers are already attached. They are in like-new condition, but they are used items, so please understand. If you have any questions, please feel free to ask. Thank you.
