4 sealed boxes plus one "bonus" box. I've got too many things to photograph and sell to count loose sheets. Consider them a freebie. I got this lot a year or so ago, but I won't be using it anytime soon. For any of you with unfinished projects due to lack of supplies, now is your chance! 4 sealed boxes have expiration date of 10/2001. The open box is from 03/1993. $450 shipped anywhere in the US. 10% discount to those who choose to pay with a money order or cashiers check drawn on a US bank.
