"Stingy" is the re-design of washing powder bags, which simply turns a torn corner of washing powder bags into a quantitative ladle.
Its most distinctive feature is as follows, when the clothing is much, we can fold in the bottom of the quantitative ladle a small part; while the clothing is less, then we fold in the bottom a little bit more.
In general, ordinary washing powder bags tend to bring out waste because they are lack of quantity control while dumping, nevertheless, special designation of "Stingy" avoids it well. "When stingy become a thrifty", our cities will become more environmental-friendly.
