Matcha Tea Bowl Blue Grey Brown, 5" Wide

The chawan is a Japanese matcha tea drinking bowl or cup. This piece is the same shape and approximate size as chawans found online. One may also use the bowl for holding other items of course.
 
There is a signature on the bottom, but it is indecipherable. It does appear to be in English however. The piece is in excellent condition but for a white stain on the foot, which may be from the remnants of a price sticker at some time in the past. See photos.
