These mats used to last much longer. The last two times I purchased them, I literally burned through them in a matter of a month. I opened and started using my current pack on November 28th, it is now December 17th and I have 14 mats left!! I do use them a lot, but again, I've been buying them for a while and suddenly they suck. I maybe get 5 cuts before the paper doesn't stick well enough, even when using my brayer. Very disappointed.
