I received this about four years ago and kept it at home without opening it. About a month ago, I mistakenly opened it, thinking it was hand cream, and used a small amount. So, it has been opened, but there's plenty remaining. It's been stored at home for a long time, so there are some slight scratches on the packaging, but it doesn't affect the use. To prevent the cap from opening during transit, I will secure it with tape and ship it via Yu-Packet Post.
