These Lego tubs are great. We bought one for my 8-year old son and what we love about it is that he can build anything he can imagine. It's not like the kits where you're supposed to build just one thing. These can be used over and over and such an easy cleanup to throw them all back into the tub.
You cant go wrong with legos, still a fav in most homes including mine> great box to keep them contained> its a goody!
This is the perfect Lego starter set for any 4-year old (or even 3-year old). It has a ton of different kinds of pieces and a box for storage, which is great because these things go everywhere. And when you buy other sets (which are inevitable, at least in my house), you can fit some more into the box too. Love legos - they keep my son and all his friends busy for hours. Only problem with Legos is that they can get expensive, but this set is a great value for your money.
