Do any anime messenger bags use a zipper or a clip instead of Velcro?
I own a couple of licensed anime messenger bags (2 Saiyuki and 1 Samurai 7) and they close via a snap closure only. It is very difficult to just “lift” the bag open and steal something because the flap is up against the bag quite snug. However, you can apply a fabric adhesive velcro to go underneath the flap of the bag for extra security (you can purchase this at any Michaels or fabric store. Just make sure it is a “fabric” velcro adhesive).
