The fluffy, light and cute rounded shape is from the very popular washable bag - fuwari - series. It can be easily washed even if gets dirty, so it is also recommended as a mother's bag. The main pocket is large enough to hold a 600ml plastic bottle and a long wallet at the same time. The front zipper has enough capacity to hold a bi-fold wallet, and the side pocket can hold a plastic bottle, smartphone etc. The slightly longer handle makes it easy to put your arm through!
