Add some cardboard or paper to what you make with with these Bild clips. Now you can incorporate your drawings or notes to give your characters more character. You can also combine the structural qualities of cardboard or chipboard with the other attachments. The OGOBILD attachments are interchangeable, safe, and functional toys you can use to create anything you can imagine. Now you can download, modify, and print out your own custom pieces.There are two sizes. One is for thin cardboard, the other is for even thinner things like paper. You can print at a lower resolution with supports.
