This is a health device I purchased a few years ago at the Kudamatsu SA on the Sanyo Expressway. You place your feet on it to stretch your Achilles tendons. I haven't used it much, and it's been sitting in the corner of my room. Please check the photos, as there are three dents and what appear to be stains. I don't think it has been used much, but it is a used item, so please refrain from purchasing if you are concerned about its condition. Instant purchase is OK. I will ship via Yu-Yu Mercari. Size: (approx.) 33.5 cm x 24 cm x 15 cm In my personal opinion, it has a simple design and feels sturdy. Thank you for looking.
