This is a Jinbei (traditional Japanese summer wear) for a baby boy. It has only been worn a few times and has no noticeable stains. My son used to wear it, and I've been storing it folded. There are no smokers in the family. As far as I can tell, there are no major stains, but this is a used children's item, so there may be oversights. Please judge from the photos, and feel free to ask any questions you may have!
