It’s amazing how a simple piece of paper and a little inventive cutting and folding can create such an intricate and playful design. You will want to hang out in this Jungle Gym for hours imagining all the different ways you could scale to the top. Jungle Gym was designed by Masahiro Chatani, a Japanese professor of engineering and the founder of Origamic Architecture. This card is made in Japan and measures 16cm x 11cm when closed. Envelope included.
