Little slippery due to varnish, but great size and shape; quality wood.
I like the shape and the size of the wooden blocks. I think the varnish makes them little bit slippery, especially if you sweat. I was surprised how light the blocks are; I also have Manduka cork blocks (same size), but much heavier, which I prefer for strengthening of the core, shoulders, etc. I'll give it four stars.
