i got them from puroexpress. honestly, i was a bit disappointed with the quality of the cutter, the blade is extremely thin and the plastic feels fairly cheap. oh well, it was only 20 bucks for a new toy, and the vendor was very attentive. I haven't used it yet, just came in today, maybe i'll have better luck with a cut, thats what really matters anyway. my #1 is still my palio.
