I have been storing this at home. Upon listing it, I opened one bag. Because it was stored at home, the colored pencil case and the bag stuck together when I opened it. (It's a little difficult to take them out of the bag) However, there is no stickiness on the case itself, and it can be used normally. The adhesive on the opened transparent bag was a little sticky. (Please check the photos) ※There is no problem with the contents, but please purchase with your understanding.
