great! this is a nice light colored wood and pieces are smooth - no splinters - and no chemical smell from being treated before importing from china or wherever (made here in the US) I keep a soma cube at work to work on during breaks sometimes. I dont always solve it right away but they say even a 5 yr old can find a solution IF they don't give up! I think everyone in my area at work who's seen it on the table in the breakroom has at least tried to solve it for a little while!
