I bought this tumbler as a gift for my cousin whom I'll be visiting soon. I wanted to give her something to represent my home state and this fit the bill perfectly

Concerned what you are drinking from may be toxic like plastic or even break like glass, you might want to try safe and secure stainless steel. The MD. flag tumbler at 12 oz. is the right size. It's easy to clean and the handy top with slide access makes it almost spill proof and it comes in several colors. Route One reported it might take awhile to receive my items; glad this was one time they were wrong: ordered on Thursday, items in my hand in Florida on Saturday. WoW!
