The Luftmatz cube also works on the principle of airmats: The balloon is inflated firmly in the cotton cover, twisted a little and placed under the closure tab. The 6-color cube is ready. Although the sides are slightly curved, this colorful cube is great for rolling. You can also design the cube yourself with fabric crayons. It is used in elementary schools, at children’s birthdays, or at leisure time for group games. Depending on the application, colors, numbers, names or letters can be rolled. The cover can be washed in the washing machine, which means that, with suitable writing materials, different lettering is possible, depending on the desired use. The Luftmatz cube is also suitable as a stool for children. The Luftmatz cube is made of strong “jeans” cotton.
