It is used for pack test. The price is expensive a little but can be used with confidence ...
The transparency is outstanding so the result is easy to understand, and the size also comes in handy just fine.
Previously we purchased a small amount at Tokyu Hands, but our shop is relatively cheap and effective in cost savings. Goods have high transparency and luxurious feeling.
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.
