This is a polyester han-eri (half-collar) with chirimen (crepe) and lace trim. I chose and attached this to a single-layered juban (undergarment) a few years ago when I had the juban made. The juban was made of a cool, comfortable material, so I removed this han-eri and replaced it with a white one. I have stored it without using it even once. I didn't see any stains, scratches, or dirt, but I am just a regular person looking at it, so please understand if I missed something. ★Please refrain from purchasing if you are looking for perfection or are overly concerned about details. ★Returns are not accepted after purchase. ★Excessive price reductions will not be considered. ★Comments will be responded to on weekdays from 6 am to 12 pm and from 7 pm to 10 pm.
