Hey @olanmills, see Rico’s comments on mini cards in his travel / storage guide. He said
For the mini cards (spec choices and add-on buildings):
- I only tried some Mayday Mini Chimera Game Sleeves (these were the non-premium type, they come in a pack of 100 with a red cover), which are officially 43mm x 65mm. They’re a little long (the 65mm bit) but fit perfectly on the sides. This form-factor isn’t available from a lot of the manufacturers, and my local store didn’t carry it so I ordered them from Amazon (which delayed this particular post).
- The Premium ones say they’re 41mm x 63 mm, which is weird because that’s the size of the Mini-USA ones. I haven’t tried them, but suspect that’s just not going to fit, given the fairly perfect fit of the 43mm non-premiums.
- I was worried I’d have to get the Mini Euro boardgame sleeves (officially 45mm x 68mm), which would be even longer, but didn’t end up trying them.
- When all stacked up, they puff up a little and one or two wants to float out of the designated holding area in the deluxe box, but it’s not a big deal.
- If anyone doesn’t like sleeves, by all means skip them, (especially for the mini cards which aren’t handled much anyway).
