sleeves are made of 6 mil crystal clear vinyl. Our sleeves come
in four sizes. They are designed to fit our 58mm, 63mm, 66mm,
and 80mm cut discs. The 80mm minidisc sleeves come in an eight-up
sheet. All other sizes come in ten-up sheets. The sheets
are superior to individually-sleeved discs for shipment, carrying, and
distribution. CCT will separate sleeves for a nominal fee.
Here are the dimensions of CCT's standard sleeves.
