Hi guys, just wanted to share this with the café as it has helped me immensely.
Years ago, I was into magic the gathering (a trading card game) I recently rediscovered my collection in an old box and I realised that sleeves/protectors would be the perfect size for standard bikes. I now use them to store all of my gimmicked, gaffed cards and packet tricks that I keep separate from the deck. This means that they no longer get dirty in my pocket, wallet or cabinet! If you are interested and are having trouble like I was. I've found them quite cheaply on amazon in the UK:

and here in the US:

I hope this helps someone!
Have a great day

Matty Freakin Whipple just told me about using the metal wallets for the same purpose. Seems like an awesome idea. Just passing it on

I use those metal case they make for carrying credit cards to travel. It's got tons of slots and takes very little space.

I would add if you are going to use the deck protectors for your cards, go to your local nerd store. Someplace where they play TCGs. You will find storage boxes and sleeve much cheaper than amazon. How to find one of these shops? http://locator.wizards.com/#brand=magic I get the 600ct boxes to hold gaff and gimmick ed decks. You can get like 12 decks in one. I like to put a slip of paper in between each deck so I know where they are. I use the nine pocket pages as well for sets of three or fewer per pocket. Then they have small plastic boxes that hold are made for 100 50 and 25 baseball cards.
