Lego Duplo 10460 Green Building Plate Base Board 10 x 10

What you're getting

This green baseplate gives your little one a proper foundation for building, literally. At 24x24 studs, it's sturdy enough to handle whatever they're stacking at any angle, so their creations won't go flying across the room the moment they sneeze.

It's designed to work with your existing LEGO DUPLO collection, and the blocks come off easily enough that you won't spend your afternoon prising them apart with a fingernail. That means they can get on with playing independently while you actually get something done.
