This is soooo cute! It is a cup of “ocha” or green tea. It is just like the green tea you get at sushi restaurants as these restaurants usually use bagged tea. You can see the little bag in the tea! It is sitting on a hand painted square with a leaf shaped plate with tofu on sticks covered in miso!
It is on a silver tone adjustable band that will fit most ring sizes. It measures about 3 cm wide (1 inch) and 2 cm high (.8 inches).
