Thank you for viewing! This is an eco-bag by yururiku. The bookmark-like string is the accent! It comes with a string (string color: black) that is inspired by the spine of a book. When carrying it around, fold it up small, roll it up with the string, and make it compact! An eco-bag with long handles that makes you want to put books in it. This chic and easy-to-use eco-bag is suitable for all genders. It has long handles and no gusset, making it convenient to carry around. Material: 100% cotton (4 oz) Size: W330xH390mm (no gusset, B4 size compatible) Handle length: 650mm
