* I received this product to review on my blog, in order to give an unbiased review of the product, positive or negative. I received a big bag of 500 building bricks. My son Zachary loves building bricks. He uses his imagination and builds houses, rockets and much more. We have had all different brands of Legos. They tell you they work with lego bran bricks. Sometimes other brands are not made as well and they don't fit together or they break. Well these bricks do fit with lego blocks, mega bloks and all others. They have a guaranteed tight fit. With these bricks you get a big bag of bricks for less money then the name brand sets. These bricks are not affiliated with or endorsed in any way by lego or mega brands, or a registered trademark. My son doesn't care about names of the bricks. He just likes to have multiple sizes and colors so he can build what he wants.this is a great product. This is definitely one to add to our Christmas gift guide. For more information click here.
