I had kept it unopened for a long time, but the nylon bag had deteriorated, so I replaced it. I also took a picture of the label that was attached at that time (Photo 1). This is a very rare item. It's a very cute pink chopstick set. I think it's a beautiful item in good condition, with not much noticeable dirt. However, it is a vintage item. If you are concerned, please refrain from purchasing.
