The Portable Chinese Gong Fu Ceramic Travel Tea Set is a brilliant invention. It includes a 150 ml gaiwan (small teapot), two 70 ml tea cups, a strainer and a carrying bag. The gaiwan also has a silicone sleeve (your choice of red or gray) that protects your hand from the heat.
When stacked together for travel, the whole thing becomes quite compact. It is only 5.9 inches (15 cm) tall and 2.7 inches (7 cm) in diameter. If that is too large, there is an even smaller version that removes the strainer (but still includes one that is built directly into the spout of the pot).
This set is ideal for taking on a trip, so that you can brew your loose tea leaves in your hotel room or outdoors somewhere. It is not well suited for having a cup while on the move, like in your car.
I love that this set includes 2 cups, so that you can share a tea time with someone special wherever you may be journeying together. The carrying bag is a wonderful touch, too.
