green buyer shopping bag by leon zhu from china

This way of（bring your own shopping bag）can decreases the use of plastic bag and reduces pollution. However, it is not nice looking nor convenient to carry an empty shopping bag in hands when shopping.
Green buyer has a shell and you can fold and roll the bag into cylinder form and put it into the shell making it very convenient. Plus, when you come back from shopping, you can put the handle line of shopping bag in round hole in the middle of shell and treat the shell as the handle of bag. Because the handle line doesn’t directly oppress on the palm, you would not feel uncomfortable even carrying the heavy bag for a long time.
