The anti-gravity intersection gives you a model where, from the right angle, balls can roll uphill.
You will receive two crafting sheets with punched and pre-folded components. With the help of glue, the object shown in the pictures can be created in just a few minutes. You will receive German-language instructions that explain the process step by step. Balls are not included.
