A box, designed for a 3D puzzle, invites you to geometric wonderland!
A novel, bi-axially twisted curved structure is from a single PET sheet.
You can unfold and refold without tools or glues, experiencing how shapes transform between 2D and 3D. The box of geometric magic cheers your creative mind.
In essence, a “misalignedly joined two squares” is folded into 3D.
Mountain- or valley-folding provides mirror-image structures.
Undulating peripheries resemble an impossible object “Penrose Square”.
Providing a shaft, it spins like a pinwheel as you blow!
The box is simple, economical, recyclable, and, above all, educational.
