My daughter received this kit for xmas from Santa. From the packaging it looked promising, however, I'm afraid I have to go against the recent trend in reviews.
My daughter is 8 and found that the simplicity of this kit and the quality of the 'pebbles' produced resulted in a 20 minute play after which they were left to gather dust.
The pebbles are plastic and non uniform. Basically, half the kit is simply sticking a picture onto the bottom of these plastic pebbles and the other half is the option when you can paint your own design (difficult to get anything of real quality considering the size of the 'canvas'.
Although this kit is not expensive and expectations were not that high, I've got to say, we were all a bit disappointed with what this had to offer.
I'd recommend spending your cash on something else (egt the Klutz kits for about the same price)
