Flipside 4 wallet, can it go the distance?

The Flipside 4 wallet is a polycarbonate (hard plastic) wallet with a spring opening and several card slots with cash capabilities. It's fun to use, but is it really useful in day to day carry? Seems large for a convenient carry, but it grows on you.

Today we will be reviewing the Flipside 4 wallet. This is a polycarbonate shell wallet that you don’t see very often. The wallet is packaged in a box. You can tell the color through a small opening on the box. The wallet comes in various different colors. They have also included an operator’s manual. This has a polycarbonate shell, so it is meant to take abuse.

Now into the feature review of the Flipside wallet, version 4. The Flipside opens through a button that is spring loaded within. As we look at the interior, there is a card slot where you can insert a number of cards. Immediately opposite of the card slot there is a tray. This tray can be moved back and forth and can hold cards. It also has a quick access card slot that can fit one card. On the opposite of that, there is a cash clip. This cash clip can be used for cash, but you can also put a card underneath, as well as additional cards on top of that. It really comes down to whether you want to have cash, cards, or one or both. On the outside, it has an attachment where you can put various different attachments on the Flipside itself. This one provides a grippy elastic band. It allows you to put additional cash, cards, tickets or whatever you want for quick carry.

Now to the cash and card insertion test. I think a reasonable minimal carry of cards is four to six. The company recommends up to eight cards and ten slips of cash. What I really like about this, is how easy it is to put more cash or additional cards. U.S. and Australian currencies work great, but Yen and Euro won’t fit folded over just once. You would have to fold it over twice to get it in there.

It is designed and manufactured in the United States and is made from a high strength polycarbonate and aerospace grade aluminum, which I am sure is a crush resistant design. With the introduction of new technology, there is always a concern that something might go wrong. However, this material is kind of cool. As I mentioned, the external piece is attachable and detachable. It is a piece that is provided by Flipside which actually attaches to the outside, using the provided holes. It also provides the ability to buy other items.

The convenience of being able to get the cards out fairly quickly is an added bonus. However, there is a concern of the ability to get the lower cards out without pulling everything out. With it being a shell case, you would expect that one of the features would be the ability to seal it shut with some kind of rubber seal, but there isn’t. Therefore you could get dust or water inside. A rubber seal would have been a nice feature to this.

By way of measurements, it is 4.3 x 2.8 x 0.8” and weighs 85 grams. It is pretty bulky until you get used to it. It is also pretty expensive for a piece of plastic.

Now for the final score. For quality, a 3. Price, a 2. Features, a 4. Usability, a 4 and perception, a 3. That gives us a final score of 3.2 out of 5.

Flipside 4 Wallet

This wallet is constructed out of heavy-duty polycarbonbate and aircraft-grade aluminum interiors to prevent your cards from bending and cracking. For added protection, it also comes with reinforced hinges and a scratch-resistant surface.
