Congratulations to Beth, from theTea and Chocolateblog! She is the lucky winner of the Mighty Leaf mug. I took my mug last week to CA. It worked like a charm! Even non-Mighty Leaf bags stayed in the dome. The technique I used was to give a gentle tug to pull the tip of the bag through the slit. The bag then sit up there perfectly, allowing you to drink tea that is steeped "just right" - neither weak nor bitter. The tea stayed hot for a long time, too. Enjoy, Beth!
