Brewing grandpa style in a simple tumbler like this is about as simple as it gets. Toss in a gram or two of your favorite tea and keep adding hot water all day! Watching the leaves unfurl and float around is very therapeutic! 250ml tea brewing volume Double wall borosilicate glass construction 6.5cm Wide by 16cm Tall ( 2.5" x 6.25" ) These are left over from our original "gongfu2go" portable tea brewer. That project didn't work out so well and we've got a lot of these left over. We removed the troublesome filter and brew basket. There is no lid. This is just a simple glass brewer. These are perfect for brewing in the office or when you don't have time for a full gongfu session.
