Platinum Limited Edition Izumo Precious Wood Karin Kobu Fountain Pen

Izumo “Precious Wood” Series. Celebrating the Beauty of Nature and Craft.

The Izumo brand embodies the spirit of traditional Japanese craftsmanship, blending artistry and natural beauty in every detail. Platinum now introduces the “Precious Wood” series — a collection that showcases rare, highly valued woods transformed into exquisite writing instruments.

Each fountain pen in this series celebrates the organic beauty of the wood’s unique “Moku” (heather grain), a rare and mesmerizing pattern formed through the natural twists and growths of the tree. Over time, the wood barrel develops a deeper character, inviting you to experience the joy of its gentle aging.

By removing the step between the cap and barrel and eliminating the clip, the form achieves a beautiful sense of unity, allowing you to fully appreciate the texture and warmth of the wood in your hand. With only a minimal protective coating applied, the surface will evolve gracefully with use, acquiring small marks and a patina that tell the story of your time together, a true “nurturing fountain pen.”

The 1st Edition: Karin-Kobu (Amboyna Burl)

The debut model in the Precious Wood series features Karin-Kobu (Amboyna Burl), a rare wood found in Southeast and South Asia. Amboyna burl forms when the tree develops natural growths on its trunk or roots, resulting in intricate, swirling patterns that resemble ripples in water.

Each piece displays a one-of-a-kind heather grain, a natural artwork shaped by time and chance. Knots, bark pockets, or tiny natural imperfections add to its authenticity and charm, making every pen a singular expression of nature’s beauty.

Embrace the living elegance of the Izumo “Precious Wood” Karin-Kobu Fountain Pen, a masterpiece that deepens in beauty as it ages with you.
