This is an item I purchased at a glass museum in Otaru during a school trip. It seems they are no longer made. It's made of beautiful light blue glass. The box has discolored due to deterioration, including the cellophane tape, as it's been a while since I bought it, but the puzzle itself doesn't seem to have any noticeable scratches. You can enjoy it as a puzzle, but it breaks easily if you apply too much force. I broke a different color version of this one that way. Because of that, I've opened it, but I was afraid of breaking it, so I've mostly kept it in storage without touching it. Please understand that this is a used item before purchasing. Type...Other
