I have the Periea Handbag Organizer (Chelsy model) in small and large. Both of them are useful and adequately made. I generally favor bags that can hold a lot of stuff and sometimes, it can be a real pain in the butt to dig around the bag to find an item (i.e., wallet, keys, glasses, lipstick). Also, when I decide to use a large bag, my stuff gets tossed around. These organizers help on both counts. They enable me to store the items in easy to reach compartments, and they significantly reduce movement and tumbling. I'm happy with both. I added a few photos for size comparison :)

This purse is AWESOME! I carried it all over Italy for a week and it worked very well. I (luckily) was never a victim of pickpocketing, but I a felt very safe with my money in this purse. I kept my cards in the slots and loose cash and change in the side pockets in the same zippered compartment. In the other locking compartment I carried sunglasses and random other items. In the small, non-locking front pocket I kept tissues and chapstick. I used the back non-locking pocket for maps and my collapsible water bottle. When my water bottle was in use I attached it to the side of the purse and that worked well also. The purse has a surprising amount of room for the size. I love the midnight blue color. It goes well with everything and doesn't make you stand out. I would buy again.
