The price has now been increased to 3,960 yen, which is the regular price. I used these indoors for about an hour during a wedding and a pre-wedding photoshoot in traditional Japanese attire. They were washed and then stored at home. They are size 4L, but I usually wear shoes size 27.5-28cm. They have 5 hooks and were easy to wear. Please note that there may be creases due to packaging. No stains, tears, or odors.
