ZENFUN4 Pack Baseplates Building Plates for Building Bricks, 10'' x 15''/25.5x38 CM, Classic Build Baseplates Compatible with Major Brick Brands, Grey

Work great. Work with Lego brand legos. Some fit a bit snugger on the plate but you can get them to work. Might need an adult to help at times

The perfect size to cover my son‘s table to make him a Lego play area. We were able to use double-sided tape just to get to the desk and it worked perfectly. Now he has so much fun making a Lego city. Great size and quality and way better Price than a Lego store.

These work better for Star Wars sets involving numerous smaller pieces (like droids and vehicles) and characters (like clones and battle droids) rather than complete like Harry Potter sets like parts of Hogwarts and buildings.

Love these!! They work great!

These are fantastic! Just as durable and precise as the name brand, but in dimensions that they lack. Great for resurfacing into a play mat or, in my case, using as bases for art-style displays and brick "posters". At current pricing, value is unbeatable at less than $5 USD each when you purchase a 4-pack. Wonderful!

I bought these because I needed to cut them to fit some plastic storage cases for my son's LEGO builds. The LEGO bricks fit the base plates but not easily. It took some maneuvering to get the completed sets attached, but they did work. I only lowered my rating by 1 star because the imperfect fit did cause me to break several of my son's sets while trying to attach them, and he was not happy.

Works great for my son’s diy Lego table

These are thick and sturdy and works with the most popular brand of building bricks. Good value.My only dislike is that the do not lay flat. When placed on a flat surface, the middle of the plate is about 3/16" off the surface. They are bowed up in the middle. Even after building on them across the middle with 30 bricks, they still pop up in the middle.If you need building mats for general play, these are fine. If you want a mat to display your creation, these are not the ones you want.
