I was really excited for this the moment I laid eyes on it. It's a decent size, would hold roughly 1 normal size can of whatever you like. (For me it would be Coca Cola.) Immediately tested the seal out by filling it about halfway with water and turning it over with the lid on. Seal did not leak, but some leaking around the part you drink out of. Of course, I was holding it directly upside down and really, some leakage would be expected from doing that<br /><br />Being a huge fan of Fallout, I will probably be buying a few more.
