The Red Eye Glass 14-inch Twice Baked is a stemless tube with a built-in donut-style percolator, so there's no separate downstem to remove or break. The donut perc filters and cools the smoke as it passes through, for a smoother draw, and the stemless design keeps things simple and easy to handle. At 14 inches it's a good everyday size with a stable base. The twice-baked donut look gives it some character. It's built in borosilicate glass for durability. A tidy, well-filtering daily piece for someone who likes the simplicity of a stemless design.
