Don't waste your money. They don't even bother to give you the correct size mandrel for the piece. So if you don't have one handy, spin the wheels by hand and look stupid. I'm sending them back because I'm ashamed that I bought them. Also, there must be some other definition of "grain" that I don't know as there is almost no difference between each color and that's probably why they don't send a color coded table, you don't need one.
