Last package just arrived this month from Singapore and one of these is the bag with a stroller in the image below. My sister said this bag is used when you go to wet market. If you are going to buy some frozen foods the bag will be the right place for all your market needs.
At first I thought it is a traveling bag. This bag has a wide storage so all styles of clothes can be fit however the bag doesn’t have lock or zipper so I guess this is not safe at all especially in the airport.
