Far too expensive, but very fun.
The box looks like a normal carton box but when you come closer you'll notice that it's soft and that you can sit on it. The box is soft and can be coated for outdoor use on request. (please let us know during ordering.)
Size: 45x45x45cm / 18".7" x 18.7" x 18.7"
Also available in other colours on request (RAL, PANTONE and NCS colours)
