My wife says to me, "I just want to go to the grocery store and run some errands, and I don't want to lug around a big bag." So I designed and made this little purse that does it all. She has the option of leaving it in her bag or just grab it and go. It is 4 3/4 x 3 1/4 inches and easily fits in a pocket. The center zipper pocket opens wide to let you see your change. The keys suspend from the case on a leather thong with a split key ring and can be flipped inside the center zipper pocket for storage. The back zipper pocket is perfect for easy access to a bunch of cards or folded cash. It holds a lot more than you would think, certainly all the essentials.
