6 Pack Large Building Brick Baseboard in Green, 10 x 10 Inch Baseplates Compatible with DUPLO,MEGA, Baseplate for DIY Play Table or Wall

My little ones really like these base boards for building their projects. They hold well which little fingers need sometimes.

Grandkids are enjoying them

These are super thin and work with name brand blocks. We used them to cover a train table to convert it to a lego table with the big bricks. We get lots of play out of these.

Took 1 star off because they don’t lay totally flat. But they hold duplo just fine. I prefer them to the Lego brand because the corners are square so they line up perfectly.

Works really well, very durable. We build duplos on it often. Pretend green for grass, blue for water, grey for sand when building. Can’t tell difference from the LEGO brand ones and more affordable.

I ordered a ton of Duplo knock off bricks recently, and as fun as they are, having a foundation to begin work on made it easier to teach my daughter how to build structures and more complex shapes. The pieces are fairly large, and you can always stitch multiple together using bricks to link them.One gripe I have is that these cannot be stacked with bricks in between them. The underside of these foundations are not usable - only the top surface is. So, if you want to build a multi-story structure, it won't be with these. I've also seen these mounted to tables and walls just for this reason.Overall, I'd recommend these. They've held up over the months we've had them, and once you add bricks to them, the floppiness/warping is non-existent.

NOT VERY FLAT， but cheap and ok to use

We bought this for our duplo Lego’s and indeed it was compatible. Does have a slight bend in the middle but once you put legos on the board it straightens out
