I am listing this because I have graduated. It is leak-proof and keeps things cool, so it was very useful in the summer. The exterior has some minor scratches and signs of use, but I did not find any noticeable scratches or stains. The replacement parts such as the straws have slight discoloration (from tea), so please replace them if you are concerned. This is a used item that was used by a child, so I would appreciate it if you are not concerned about minor details. I am listing various straw mugs, so I will offer a discount for combined shipping.
