These are actually called "Zaks", by Ohio Art

Those things were terrible!! You could build a sweet box...thats bout it! ahaha

I have a ton of these that reside in my closet somewhere. I use to build small furniture sets, everything from beds, lamps to kitchen sets out of them as well as many other things.

My Cousin and I used to make balls out of them, fill the balls with loose ones and take them outside and play catch! It was so much fun....used to get in trouble though cause we would lose some everytime they crashed and had to be rebuilt!

I used to make balls out of these, too. I found that if you made a bunch of little pyramids out of the triangles with the bumpy bits on the face of them, and then used those to build the ball, you could play catch or even soccer with them without them falling apart... just try not to bounce them off the walls too hard.
