Ansty Labs’ Pixl is a unique and fun take on building block toys. Instead of pieces with grooves or studs, each Pixl block has a magnet inside that automatically rotates so that it will always stick with another Pixl block. Pixls comes in four sizes and 52 colors.
EverBlock’s interlocking plastic blocks are like giant size LEGO bricks, but are sturdy enough to create temporary or semi-permanent partitions, walls, and furniture. They’re also perfect for building playhouses for kids and pets. Play with their online 3D builder here.
