I'm going to order some of these on ULINE.COM, and I have 3x5 index cards I use.
I'm debating if I should get the 3x5 sleeves or the 4x6, reasoning is I don't want to get the 3x5 sleeves and be just too tight so the cards won't fit in, anyone thing they will fit perfecftly or should I got with the 4x6's?
