I think these could be used in both summer and winter. It's like a corset! This is a short type, so it's not obvious to others that you're wearing it! I bought each one for about 3000 yen! It's about 6000 yen total. I'm not using them, so I'm offering them to someone who will! The box is also dirty, so it's not suitable for those who are concerned! ⚠ The item will be shipped as is in the image, in an outer bag, so the box may be crushed. Please be aware of this beforehand!
