Strictly BriksCompatible with Lego Classic Stackable Baseplates, Building Bricks for Towers, Shelves, and More, Space Themed Colors, 4 Base Plates & 30 Stackers, 6x6 Inches

My son loves the special stackers that let these plates become buildings and towers. The fit together nicely. My 7 year old is able to build with them easily (This is his first set of "little legos" as we transition away from Duplo size. Highly recommend this product line.

Grandson has so many legos and runs out of room to build things on. He loves this. Immediately after opening and his dad helping to put this together--legos were occupying all the different levels.

I liked the small size of these for my keys D's to display their creations on without taking up a lot of space. The stayed together well and they are able to hold Mega Construx and regular Legos(which is primarily what we use)

Legos fit just fine, not the tightest fit though. Kids like it.

Good set, exactly what it says it is. Fully compatible with Lego or MegaConstrux or similar building blocks. Six inches is rather small for a base plate, but quite large for a tower. The base plates are a little soft and flexible, making the compatibility questionable in the full tower construction due to the base plate flexing a little when only the Stackers support pillars(also a little flexible) are used. Connections are a little weak, but given the small size of the Stackers support pillars that's to be expected. When used with another Strickly Briks set with more bricks it stabilizes and works perfectly. 30 Stackers, but that end up with eight blue, eight dark grey, then seven black and seven light grey, so uneven colors. I would suggest the gray scale in future sets(or solid colors), but the blue is pleasantly darker than shown on my monitors and matches the old classic "space" themed sets Lego used to make pretty well. Again, by itself it's too flimsy to work as a display or storage shelf, but with additional bricks to fill things out fixes all these issues.

I bought the round ones....love the product!

This is so small, it is basically useless.

Thank you so much, exactly what I was looking for.
