2.5" Cardboard Holders - Window Size?

For the 2.5" cardboard holders, I picked up some that the window measures just under 1 3/4". They measure 1 11/16", which makes the chip a little tight when the holder is sealed (see image below). Even though they advertise 1 3/4", is this normal to be undersized, or did I buy wrong ones?
Thanks,
Marc
