It is a good item. Although I am using 300 or more, there are no defective products such as liquid leaks so far, and I receive the impression made carefully. Size is also large and small, it is convenient to align. However, the size of the largest 110 ml has not been used since it has been spilled all the way in the bottom before the bottom. Small size is quite solid. It did not crack even if dropped from the 70 cm desk to the floor.
