ya. i never bought rainbow brush but seems interesting from their web site. also noticed they are at youtube as well. i saw kids using the other stuffs what you call them rainbow art kit or whatever from tv but did not hear good thing about it. One of my neighbors bought rainbow art kit after seen on tv but they told me it was a junk.
Well, tv can be bad and I never buy things from tv anyway, they show things are not true and most likely digitalized and all these pressures drive me crazy –
buy this get this free, hold, more free and bonus and more free. Yaaa you are right, if it is free, then either it is junk or no good.
