A generous sized mug that we LOVE. Let us count the reasons: 1. Large infuser with tiny holes so you can brew every type of tea from finely cut rooibos to fluffy white tea. 2. The lid doubles as a coaster for the infuser and has a rim that prevents your tea from dribbling on your desk. 3. The mug is microwave safe and everything can go in the dishwasher. 4. Made with excellent materials by a great company. They request third-party testing on all materials and glazes. For an all-around, everyday infuser mug, the Curve mug can't be beat! 15 Fluid ounce capacity.
