So you love hot and iced tea all throughout the year, but don’t like the grit and loose tea leaves that can escape from tea bags and machines? This tumbler has a strainer in the cap to catch leaves, grit and other foreign substances from your tea before you drink it. It’s made of double wall insulated borosilicate glass, so it will maintain the temperature for hours. Clear design with metal lid.
