Backpack / bag combo
Made of cotton canvas, this bag is thick and sturdy. You can use it as a shoulder bag or as a backpack, it's convertible! It's also possible to hand favorite keychains to the rings at the top and you can add pins on the front.
NOTE: This isn't a school bag, if you use with heavy books, I cannot guarantee it will hold. It's perfect for wallet, knick knacks, hand desinfectant, keys, water bottle, etc.
