Each Cuble arrives the size of a greeting card: 5.25 x 7 x 1/8 to be exact. This is neat because you can mail a Cuble right in the packaging with only 2 stamps. Once you have your Cuble, the first step is to simply pop out the pieces from the panels within the product. Cubles are made of an industrial strength paperboard that is 100% recyclable. You build a Cuble by folding each piece along the pre-scored fold lines. This is a great feature because it ensures you can easily fold every part correctly. As you fold each piece up into a 3D shape, you insert pre-cut tabs into open slots by color and number. Once you have built each separate piece, you will learn how to hold a Cuble together utilizing the patented key-joints. With your Cuble assembled, you can then do some fun stuff like make accessories for your Cubles or even shoot a stop motion movie!
