[Size]: Per piece: φ90mm (drinking rim 80mm) x H115mm / 156g [Material]: Borosilicate glass Sold in sets of two, and delivered in a dedicated case. A Japanese instruction manual is included, making it a great gift option. Each piece is hand-blown by artisans, so there will be individual differences in shape. You may see lines, bumps, or circular patterns on the inside and outside surfaces, and there may be air bubbles, but these are not defects. It is dishwasher safe. To clean, use dish soap and a soft sponge or cloth. The bottom has small air vents (small bumps) to create a double-walled design. This product is a genuine import from Bodum Japan.
