Adachi Shiki says it cut everything back to show the beauty of the paper, passed a 10,000-cycle open-and-close test by a public testing body, and gave it a warm feel that keeps a pen from sliding too much. ## What award did it win? **It made the Good Design Best 100 for 2026 and won one of only three Good Focus Awards [Design of Technique & Tradition], given as the SME Agency Commissioner's Award.** Its award number is 26G030128. The [G Mark entry](https://www.g-mark.org/gallery/winners/34249) says the judges valued a maker re-studying a material it had worked for decades, finding a new property, elasticity, and turning it into a product.

Vulcanized fiber is a dense, tough board made from wood pulp and cotton. The JDP judges note that it is plant-derived but about as strong as plastic or wood, and that its use had shrunk to boxes and industrial parts before Adachi Shiki found it could act as a spring. ## How does it compare with other clipboards? **It is lighter than the MDF Penco and pricier than a plastic clipboard, and it is the only one here with no metal at all.** | Clipboard | Board | Clip | A4 weight | |---|---|---|---| | Paper Made Clipboard | Vulcanized fiber | Formed fiber spring | 220 g | | [LIHIT LAB Mutual](https://stationerytimes.com/guides/lihit-lab-mutual-folding-clipboard/) | Polypropylene, folds to A5 | ABS resin | Not published | | [Penco Clipboard O/S](https://stationerytimes.com/guides/penco-clipboard-o-s/) | MDF | Metal | 370 g | Choose the Paper Made Clipboard for a desk or studio piece that ages like paper; choose the Mutual if you need to fold it into a bag. ## Can you buy it in the US? **Not from US retailers when we checked on October 23, 2026.** Adachi Shiki sells it on its own Japanese online shop. It is also part of Hyakunen Monogatari (百年物語), a brand for tools meant to keep everyday culture alive for 100 years, Adachi Shiki says. US buyers will need a proxy service or a Japanese store that ships abroad. At ¥4,620 (about US$29) for the A4, it sits in our $$$ band before shipping. ## Where is the Paper Made Clipboard made? **In Japan, by Adachi Shiki's account.** The company, founded in 1942, says it makes its products one by one in the factory at its head office in Nagaoka, Niigata. The clipboard's own page doesn't state a country of origin, so check the package. ## Frequently asked questions ### What is vulcanized fiber?

JDP's judges note it is plant-derived yet about as strong as plastic or wood; it has been used for industrial materials and even kendo armor. ### Does the Paper Made Clipboard have any metal parts? No. The clip is a spring formed from the same vulcanized fiber, so the whole clipboard is one material. ### Will the Paper Made Clipboard warp? It can. Adachi Shiki warns that the material may warp over time and asks you not to store it with something thick in the clip, or in heat, damp or direct sun. ### How do you clean a vulcanized fiber clipboard? Wipe it with a well-wrung damp cloth, Adachi Shiki says, and don't use solvent-based cleaners, which can discolor it. ### What sizes does the Paper Made Clipboard come in?
