This is a Tupperware Handle Bowl, extra large. It has a capacity of 7.8L, more than a Super Bowl. It's great for kneading and proofing dough when making homemade bread. Also suitable for making soba noodles, udon noodles, and chirashi sushi. Tupperware has withdrawn from Japan, so these are no longer available. Are you interested? Although it is unused, it has been stored at home for a long time, so there may be dirt from static electricity and minor scratches. Please refrain from purchasing if you are concerned about this.
