In Mino region, the largest ceramic production area in Japan, countless numbers of rejects are discarded. SAI Mug recycles those chips and pieces by grinding them fine, and use them as a recycled clay. The manufacturer, CHIPS inc. uses recycled clay for approximately 20% of the material, and their boxes are made of 100% recycled cardboard.

The rejects and the cracked chips were not meant to be used for anything- but through creating SAI Mug, their goals are to give them another chance to brightens people's' tables up, and to do their share on environmental conservation.
