Normann Copenhagen Rocking Glass, Round Width: 90mm x Height: 85mm 300ml This glass is designed to prevent spills, even when tilted, reminiscent of those used on airplanes during the golden age of propeller planes. Of course, it can also be used normally on a table. Both glasses have small air bubbles on the bottom (from the manufacturing process), and one has a scratch on the bottom. Please consider this item, understanding that it is a used item stored at home. Due to shipping costs, the price is set as such.
