The double-wall design of these glass mugs does double duty: adding extra insulation for your hot beverages and creating a unique look in five different color options. Made with Borosilicate glass resistant to thermal shock, more so than any other ordinary glass.
Each mug is sold individually. Slight color variations & markings on the glass are not flaws but part of the standard glass blowing & staining process.
