"Gently shape the lingering fragrance." The COFFEE STONE Key Ring is a small circular form born from the bean residue left after brewing coffee. The rounded shape of the beans and the natural, stone-like texture add a gentle touch of color to everyday life. Attach it to your favorite belongings or give it as a gift to someone special, and you can deliver both coffee memories and sustainable sentiments. [Three Stories and Natural Gradients Chosen from Materials] Without using any chemical colorants, we have achieved a beautiful three-color variation using only the natural hues of the material. Rather than simply choosing your favorite color, you should also focus on the challenges (food loss) that arise in the coffee process. This product serves as an opportunity to think together about the future of coffee. 《Grounds / Dark Brown》 　Uses 'coffee grounds' left after careful roasting and extraction. An organic dark brown with depth and calm. 《Defect / Raw Green》 　To reduce flavor, "defective beans (green beans)" that were removed one by one during pre-roasting hand-picking and discarded without turning into coffee were used. This exquisite green color conveys the natural freshness of green beans and a mysterious elegance. 《Chaff / Light Beige》 　Uses the thin skin (silver skin) of coffee beans that peels off due to the heat during roasting. This gentle light beige color brings out the light and natural texture unique to chaff. [About COFFEE STONE] It is a sustainable material made from mineral components derived from coffee grounds and seawater that are discarded after extraction. It features a stone-like yet soft texture, preserving its natural texture as it is.
