These are the 20cm, 8M, natural wooden legs that come with the Muji leg-attached mattress. I purchased these separately when I signed up for a monthly subscription service, so I stored them without using them. As the contract has expired, I purchased the bed, so I no longer need these and am putting them up for sale. Contract date (delivery): December 2021 The delivery company attached them upon delivery, but I immediately replaced them myself. Basically, I will prioritize those who purchase at the current listed price. If you have any other questions, please feel free to ask. ☺︎
