I bought this in trifold in anticipation of our recent trip to Spain and France. I'd been warned about pickpockets, especially those in and around Barcelona, and I wanted to feel more secure. I am so glad I had it! I kept the chain wrapped around my belt, a belt loop and then fastened to itself. While entering a historic church (!) I felt a slight tug around my right front pocket, where I had stored the wallet. I looked down to see the dainty little hand of a dainty little woman pulling gently on the chain.

Fact is, I use it every day now because I tend to lose things. When driving and stopping to pay tolls, carry out, etc, I tend to take money out of my wallet and then put the thing on my lap or between my legs, and then dropping it when I get out of the car. Or I may lay it on a store counter when paying for something. With the chain it is always with me.

Inside there are six slots for credit or ID cards and one pocket with a plastic window for you license or picture of your main squeeze.

I just kept a few Euros in there and one of my two credit cards in there. I kept another credit card, my ATM card, my driver's licenses (Ohio and international) and my passport in a another great item I found on Amazon, here:[...]
