When you don't want to make a full pot of tea, this little gem lets you make the perfect single cup of tea. Just set in your cup or mug and let steep. Once it's done, remove and set on a saucer until you're ready to clean it. It's easy to fill - although you need to smooth the edges to keep stray bits from getting caught there - and easy to clean - just dump out the leaves and rinse. With all the wasteful, non-biodegradable tea bags being used, it's nice to have an environmentally-friendly way to make the perfect cup.
