The mesh of this mini tray is made of hard dried grass or very thin bamboo.
It will fit 1 small teapot and 1 or 2 small cups. I chose it, because I can use it on a Cha Bu with just a teapot. It keeps the Cha Bu dry and still lets me see the colors of the tea cloth. It's also a good proportion for a small teapot. It makes it stand out better than on a big tray.
