Masae Nagao's PÉPET turns 400 layered paper circles into a pet that moves when stroked
Takeo Paper sells a palm-size 'pet' made from 400+ stacked paper circles that flex and ripple when stroked, in 120 colors of NT Rasha paper.
Masae Nagao
What it had to solve
Japanese designer Masae Nagao wanted an object that lets people enjoy paper's warmth through touch and movement. Her prize-winning paper sculpture Pe-PET became a product that Tokyo paper maker Takeo Paper could put into production.
How it works
PÉPET is a paper pet created by Japanese designer Masae Nagao: a pear-shaped stack of more than 400 paper circles that, scooped onto a palm and stroked, flexes and moves like a little pet. Nagao's aim was to let people enjoy the warmth of paper through touch and movement rather than through display alone.
The trick is structural rather than mechanical. Circles of different sizes are layered alternately, so small spaces open between the sheets; those gaps let the stack ripple under a stroke, and the shadows they cast make the colors of the cross-sections stand out. The pear silhouette is designed to maximize both texture and movement, and the material is NT Rasha, a dense, soft fine paper available in a 120-color palette from which each pet's combination is carefully selected.
Takeo Paper's product page records that the original Pe-PET won the grand prize of Japan's 紙わざ大賞 (Kamiwaza Taisho) paper-craft award and was then commercialized as PÉPET. Each pet sells for ¥19,800 (about $124) in named colorways such as Dandelion, Sky, Tropico, Guava and Fuji, and Core77's September 2026 feature showed the layered object to an international design audience.
Why it lands
- The entire illusion is material logic: layered circles of different diameters leave air gaps, so stroking produces genuine movement with no hinge, spring or motor to wear out.
- Paper is normally a surface to print on; here its thickness, softness and colored cross-sections are the product, turning commodity sheets into a premium object priced at ¥19,800.
- A 120-color palette and named combinations (Dandelion, Sky, Tropico) let buyers choose an emotional color story rather than a spec, making each pet feel individual.
- It crosses categories — toy, desk object, gift, craft — which is what lets a paper manufacturer sell an interactive sculpture through its own products store.
What it did
Takeo Paper produced and sells PÉPET in named colorways (Dandelion, Sky, Tropico, Guava, Fuji and a limited Guri that has sold out); Core77's September 2026 feature introduced it to an international design audience as a pet that moves on your palm.
What you can take
Life can come from structure, not motors: stacking circles of alternating diameters opens air gaps that let a paper object flex under a stroke, so material logic alone creates the pet.
Since then
Takeo Paper commercialized Nagao's grand-prize-winning Pe-PET as PÉPET and sells it through its products e-commerce site, with the design protected as Nagao's copyrighted and industrially owned work. Among the named colorways, the limited 'Guri' variant has already sold out while Dandelion, Sky, Tropico, Guava and Fuji remain available. Core77's September 2026 post carried Nagao's own description of how the layers move and brought the palm-sized paper pet to English-language design readers.
