Comparing
Big Building Bag 80 vs Deluxe Building Bag 150
Same blocks, same bag idea, nearly twice the pile. Here is how to decide between our two building bags.

What is the same
Both bags hold the same First Builders blocks in bright colours, and both come in a drawstring bag that doubles as storage. Blocks from one click onto blocks from the other, so starting small never wastes anything.
When 80 blocks is enough
For one child around their first birthday, the Big Building Bag is the classic start. Eighty blocks build plenty of towers and roads, and a smaller pile is quicker to put away. The pink edition has the same blocks in a pink bag.
When 150 blocks makes sense
Go for the Deluxe Building Bag if two children will share, if you want blocks for both a play corner and a grandparent's house, or if your toddler already builds big. It is also the easiest way to grow a collection that started with a vehicle or a table.
A simple rule
One child, first set: 80. Two children, or a second set: 150. Not sure how much is enough? Our note on how many blocks a child needs goes into more detail.
