We have had for our daughter (3 1/2 years) to another, more expensive game of sand inside. Now we have really bought us only to complement this set of friends and are absolutely delighted. The sand feels wonderfully soft, can be very great and simple shapes and lightly whisk together again by its "sticky" structure. Using the forms even smaller children can build great sand castles and figures. The youngest child that played with us with the sand was 2 years old and had a lot fun. As recommended age I would say: who has been playing out in the sandbox, the sand with this more than ever. It is perhaps a little more next to it, but the sand can be super good Sweep. Although he sticks in the clothes, but here goes a damp cloth and the damage has been repaired. But you should have a little more sand: we have filled the small plastic tub with 1kg. So you can well and extensively build. A purchase that has really paid off for us. Clear recommendation
