I found that 3 of my Olfa frosted rulers were inaccurate, which was very disappointing. I had just purchased one, so I took it back to the store and showed the clerk. She was willing to exchange it for a new one, but we discovered every ruler had the same inaccuracy. Bye bye Olfa.
I really like Creative Grids rulers - frosted, non-slip, and readily available in my area.
