Our son got this set for Christmas last year (since he was about 1 1 / 2years old). -Ihn Fascinated the attraction and repulsion of magnets. The stacking a plurality of magnetic parts over each other is no problem, the magnets are strong enough. -the magnets are really nice and big and easy to handle. Swallowing the ball at this age is unlikely -Our Son is now 2.4 and continues to play like it, but I've gotten another 25-piece set and a supplementary set bought separately so that it remains interesting. In order to achieve proper structures or ideas are simply more sets needed. -Unfortunately These magnets are not cheap, but we still find value for money -Papa And son inspired equally so! -g- Beautiful both with the magnets in the play area to watch
