I use mine all the time inside a larger bag. ie. speedy 40, Mahina XL, even my Petite Noe. I use it a lot when I go shopping w/o my kids because I get used to carrying only a card holder, cell phone, and keys.
I always get so many complement for using it because it is SO SMALL! It is adorable, get one! My friends call it the "baby LV."
