Putting them in a binder lets you more easily find a specific card they fit in these sheets even with card sleeves. The CD case holds any tile 4 spaces wide I keep the larger tiles separate and was able to fit every expansion in the CD case.

I buy these in a 25 pack for like 6$ on Amazon. If you have prime it's one day shipping.
