This listing is for a set of two black sandals as shown. These are commonly called "toilet sandals" and are extremely durable. Cheaper sandals around 500 yen will have their adhesive come undone at the heel or toe in a short period, requiring you to buy replacements multiple times, which ultimately adds up. I experienced this several times myself and finally settled on these sandals. Wearing these for a long time is definitely more economical. The color is a rare black (most of this type are brown). Since they are black, dirt is not noticeable. The size is M (slightly wider than usual). The actual measured size is approximately 25 cm from toe to heel on the sole (Image ②). If your foot size is 25 cm, your heel will stick out a bit, so the applicable size is likely within 24.5 cm. I think they would be a perfect fit for someone around 24 cm to 24.5 cm. The design does not expose the toes, so they also provide warmth. They also prevent water from getting in. Furthermore, they protect your toes on grassy or gravel paths. These items are unused and have been stored. They do not come with paper tags or anything. Price includes shipping. Immediate purchase is OK. If you wish to purchase just one pair, I will list them on Mercari for 2000 yen including shipping. Please let me know in the comment section.
