The sleeves are blank on the reverse with no holes. Each sleeve has a little square of waxed paper glued to the inside covering the hole. Haven't seen that before. The first 2 of the waxed paper centers are intact, the other 2 have small tears in the middle. Also, the 4 little 'flourishes' are different on the first sleeve than the other three. They are made from lightweight cardboard rather than paper.
