gaikokumama 5 This was a pretty expensive lesson bag but it is so worth it! We have 3 lesson bags but withoug gusset so it is difficult to fit more items (on some days they have to bring extra stuff like PET bottles, a t shirt and the like). Perfect size! I like that it has a hook for hanging under the table so the bottom of the bag doesn't get dirty. The cute and sparkly print is a bonus. I should've just bought this instead of buying cheaper ones!
