I love the thinlits dyes and these are really cool. The sizes are just what I can use on cards and on scrapbook pages. I tried them with Tim Holtz grunge paper and they cut well, no problems at all. I use a Sizziz electric machine with the addition of a thin piece just for thinlits and have great results.
I highly recommend these dies if you like grunge, gears, and grungy ephemera, which I do.
