Do you want a small or medium bag in Boston?

Whether Boston buys a small size or a medium size depends on its own needs.

1. If you need a backpack for daily use, you can choose a small size, which is lighter and easier to carry, and can meet the daily storage needs.

2, if you need to use a backpack to go to school, travel and other occasions where you need to store more items, you should choose a medium size, which can accommodate more items, which is convenient for storage and more practical.
