I just got into Twilight Imperium and was wondering if there are small enough sleeves I can use to put the various cards into. Does anyone know where I can get them if they exist? Thanks for any help you can provide.

Get a hold of Mike Evans. He has little sleeves for ALL his ACs, PCs, POs, SOs. PMing him on the wiki forum is probably the best way. You can find it here.

I bought a lot of clear Magic card sleeves and then used a slide cutter after putting the cards in sideways to cut them in half. It works very well.

From what I've heard, there is some company in Korea that sells sleeves "as is" for the cards that size. Alas, it doesn't seem like they ship internationally though.

Laminating the cards is an easy solution (and relatively cheap from what I hear.) It can be made to fit any size cards and it accomplishes the same end goal as sleeves, as long as you don't ever want to take them out again. =P

Laminating is exactly what I did. I already owned a laminator, so it was easy (if not real quick) to get done and works great.

Well I would like to keep them open so to speak, so I don't think laminating them is what I want. Mike Evans suggested I buy clear card sleeves and cut them in half thus having 2 mini sleeves for the cards. I tested it on some I have and they work very well. The cards fit in them perfectly so I'll be going with this. Thanks for all the ideas though.
