On my Wow! These are my new favorite tool, I mean brush, I mean BOTH!
I have already shown these around my art group and have everyone hooked. If you are a mixed media paint and gel flinger like me, it's worth getting 2 sets.
The silicone end allows for laying down design marks without worrying you're damaging your plate. I haven't used the brush end much but I've used all of the silicone ends repeatedly and really like the effects.
