Discover the calming beauty of Keyno Stay.tionery Key No.001 Serenity 25ml Fountain Pen Ink, a sophisticated teal blue fountain pen ink created in collaboration with renowned Korean ink maker Dominant Industry. Designed for fountain pen enthusiasts who appreciate expressive color, smooth writing performance, and atmospheric shading, Serenity transforms everyday writing into a quiet moment of reflection.

A Fountain Pen Ink Inspired by Stillness and Contemplation

Key No.001 Serenity is part of the imaginative world of Hotel Keyno — a fictional place where every room captures emotions, memories, and fleeting moments in time. Serenity represents a space devoted to silence, balance, and the peaceful beauty of slowing down.

Developed specifically for the Keyno Stay.tionery brand by Dominant Industry, this premium fountain pen ink explores the emotional connection between pen, ink, and paper. Every stroke becomes fluid, immersive, and deeply personal.

Elegant Teal Blue with Beautiful Color Separation

Serenity features a gentle teal blue tone that gradually deepens as the ink dries on paper. The result is a dynamic writing experience filled with elegant shading and subtle color separation effects.

Soft transitions between aqua green, deep blue, and darker undertones emerge naturally, creating a refined and atmospheric appearance reminiscent of calm lakes, watery reflections, and peaceful landscapes.

The generous ink flow ensures exceptionally smooth writing performance, making Serenity ideal for journaling, creative writing, correspondence, and everyday fountain pen use.

Designed for a Perfect Writing Experience

Keyno Stay.tionery Key No.001 Serenity was carefully developed to pair perfectly with the Keyno Stay.tionery Key No.001 Serenity Fountain Pen, offering a harmonious and coordinated writing experience where color, design, and writing feel become one.

Whether you are a fountain pen collector, ink enthusiast, or creative writer, Serenity invites you to pause, reflect, and enjoy the ritual of writing.

Dominant Industry, based in Paju, Korea, makes small-batch specialty inks for dip pens. Adapting mixing and blending techniques developed for silk-screen inks, they have developed calligraphy inks with unique mirror and metallic finishes that are expressive and beautiful on paper, plastic, film, and glass.  If digital CMYK colors are flat shades that are created through a subtractive process, Dominant Industry prides itself on its life-like colors that are created through an additive process, utilizing reflective and transparent pigments that incorporate natural light. Dominant Industry strives to create “bottled light,” colors that can be felt and experienced. This idea is reflected in Dominant Industry’s 4 different finishes: Hologram, Mirror, Pearl, and Standard.
