The best ever. They are huge! I was specifically looking for large, broad-based, insulated mugs because I have a significant hand tremor. These mugs (I bought two) mean that I can now enjoy my tea/coffee without spilling it - a 300ml drink leaves lots of room for the liquid to slosh around a bit; I can hold the mug in two hands to steady it without burning myself; and when placing the mug down on the table there's no danger that it will tip over. Answers all my requirements, and although I'm not keen on the TeaBlooms taste, I didn't buy the mugs for them, but they are pretty! I had been searching for several weeks (with some bad buys) before coming across the Tea Bloom mugs. The mugs also come with glass infusers, useful for both tea/coffee bags and loose tea, they arrived more quickly then expected and very well packed in very sturdy boxes.
