It is for display. Looks neat.
Shot glass is good. One hitter is great for ******* stuff in your mouth. The hole is way too big.
Silly but Fun(ctional)
It's a tall neat shot glass. The attached pipe is exactly as functional as you'd expect. I had the mental image of a one-hitter, but the diameter of the pipe is a bit larger than that; meaning it can handle a bit more material than I anticipated. If you ever find yourself in a situation where a pipe and shots are involved, this is a fun thing to bust out. Never fails to get a giggle out of someone
