Wow, pricey.

$85 for the Delrin 'Sport' model; $125 for the aluminum 'Tactical' model. The later model coming in at 7.4 ounces, a bit less than half a pound. The former 2.4 ounces. Seems to me that the capacity of those things is quite small. Being rigid means it won't expand to accommodate extra stuff. I can easily stuff in extra credit cards, magnifier, condoms, whatever, and my wallet just gets a little thicker.

If it remember right I got my wallet for $6 on sale. A unremarkable nylon thing that has served for ... what ... something like 25 years? Maybe a bit longer. Doesn't seem to be on its last legs so its probably good for another 20.

I'm not sure how a rigid wallet would work for me. I break mine out every six months or so and get rid of all the excess to keep it thin and flexible. Sitting on an overstuffed wallet is hard on the back.

Here again if a rigid wallet works for you, and you have $85/125 to spare I think you have found your perfect wallet.
