This new tub features a great assortment of LEGO bricks and elements.


When your toddler has graduated from the Duplo stage and is ready to take the next step in his, or her, Lego journey, the Lego Ultimate Building Set is the ideal graduation gift. With 405 pieces stored in a durable plastic box with a see-through top, this set is the perfect place to let children continue to explore their imagination and engineering skills. The Lego Ultimate Building Set contains many small pieces and is designed for kids ages four and older.

With 405 pieces, this Legos starter kit allows your child to build a variety of different things. View larger.
Use wheel elements to build a car. View larger.
Kit includes one mini figurine. View larger.

The Ideal Lego Starter Kit

The Lego Ultimate Building Set includes everything a child needs to take the first steps to becoming an expert Lego builder. It includes one mini figurine, a building plate, and a wide mix of standard bricks in various colors as well as house and wheel elements.

Following the included instructions and using pieces in the starter kit, kids can build a house, helicopter, dog, and car. The only flaw is that the instructions may be challenging for younger children, and require adult assistance.

As is the case with virtually every Lego set, your child will be limited only by his, or her, imagination and perseverance. Although the kit is designed for younger children graduating from Lego Duplos, you can be confident that your child will never actually grow out of the Ultimate Building Set. All of the pieces can be incorporated into future Lego collections.

What's in the Box

405 standard Lego pieces with house and wheel element, mini figurine, durable plastic storage case, and instructions.
