Title: Essential, but not without flaws
Review: These baseplates are important if your little one likes to build structures with Legos. I'd recommend attaching them to a board (I wood-glued 6 of them to a board, added some molding, and put sliders underneath so I could store the board under beds or sofas) so they won't flex.Otherwise, you'll definitely need to encourage your child to play with these on a table or other hard surface, and warn them that moving their constructions to another spot might result in the creations coming apart.
