These glasses are stable and have a good center of gravity through the heavy soil. You are on the wall thickness a little thicker, but this is in most wheat glasses so and will make it likely or shatterproof (the future wirds show) as a thin-walled glasses. They have no imprint and a weienglastypische form. A bottle of wheat beer (0.5l) fits in exactly. I have a glass also accurately tested for air bubbles in the glass, and only found a tiny (less than 1 mm in diameter) in the floor. For a price of 10.00 for 4 glasses are highly recommended!
