I got a 10 pack from them recently. Just tried the med - absolutely fantastic blade. I'm a big fan of feathers & 7 o'clock yellows, but my experience thus far with just this one is seriously making me reconsider my rankings.
if you can get your hands on med prep, I would not wast your time on a sampler just buy the 100pac. This blade will let you know what you have been missing however if you are not well practiced, you best learn quick. They don't forgive.
