I was pleasantly suprised by the size of this set. There are 3 paint by number scenes 22x33cm, 20x28cm and 14x21cm the paint pots are an excellent size and great colours. A brush is also included. For it's current half price it's a bargain and would make a perfectly acceptable birthday party gift for a 4-9 year old. It's worth its rrp price compared to the other more common 99p sets on the market and it's a perfect rainy day activity.
I wouldn't recommend it for under 4 as the sections to colour in are still relatively intricate and small. My 4 year old doesn't have the level of manual dexterity (or patience) to do them but my 7 and 9 year old love 'painting by numbers'.
The painting boards are thick cardboard (grey on the reverse) which doesn't bend giving a good painting surface and the paint is nice and thick.
