Men's sandals by Hawkins. I bought these last year or the year before and used them once, but they didn't fit me because I have a high instep. I haven't worn them since then. The size is 43, so they should fit someone around 27.5cm. The shipping method is undecided, but I plan to use Letter Pack. If I don't have Letter Pack in stock, I will ship via Rakuraku Mercari Delivery. No box.
