I personally absolutely love this idea, I think it's a great kit that would make a great present. As above, it is the satisfaction of making it yourself.
Basically, the kit will make a wax equivalent of one of the core 8 in the Dodo range (i.e. Hard Candy, Rainforest Rub etc etc) but without the smell or colour.
Si - I wish I could say I have tried it, but I literally found out about it around midday today. I'll be having one for myself for sure
