There are only 3 colours in this set - red, yellow and blue. However these are colours that can be mixed with each other to make other colours.
The paint is not like normal paint, it is more like coloured gel. This isn't a negative in my opinion as it works just like paint and looks just like paint when it's dry. I think this is better for younger children (toddlers) rather than older children as it seems easiler and less challenging to use than normal paints.
The way I use them is to squeeze a small amount of each colour onto a plate and let my daughter use a brush, sponge or her fingers to make pictures with. The only downside in doing this is it's very easy to mix all the colours together.
The paints can be used for painting pictures, making handprints, footprints, finger painting and general childrens arts and crafts. They're also good to make keepsakes.
Best of all the paints are totally washable. I've got them on all types of surfaces and clothing (even whites) and they have all come out in the washing machine. They also come off easily on skin - just a rinse under the tap is needed.
The advantages of this product for me would be it does what it says on the tin, it's great for toddlers, bright colours, is washable and comes in a bottle which means I can decide how much paint I want to be squeezed out.
The only disadvantage of this product for me would be the fact there are only 3 colours and the paints take a while to dry. I think the main disadvantage to others would be that the paint is gel-like, however as I've already mentioned I don't see this as a problem.
