Travelon Anti-Theft - Classic Small Convertible Backpack

I bought this backpack a few years ago, and it doesn't fit my needs. It's in barely-used condition. ** Note there are a few spots / stains on the inside flap of the purse - shown in the last photo. ** Here's the manufacturer's description for this backpack: "The Classic Anti-Theft Small Convertible Backpack carries and keeps more items organized than everyday bags.
