Limited-Edition 'Skyly Design' for Frictionless Ballpoint Pen 'FLOATUNE' Captures the Shifting Colors of the Sky from Dawn to Dusk

Astrum Co., Ltd. (President: Junichi Ishigaki, Head Office: Chuo-ku, Tokyo) will begin sequential sales on Friday, July 24, 2026, at stationery retailers nationwide, introducing the limited 'Skyly Design' edition of the frictionless ballpoint pen 'FLOATUNE (Furochun),' which delivers a floating writing sensation, under the 'Pentel' brand.

Launched in June 2024, 'FLOATUNE' is a revolutionary frictionless ballpoint pen that minimizes writing resistance to an extreme degree, offering a floating writing experience that allows users to clearly express their thoughts on paper.

This limited edition draws inspiration from that sense of 'floating' and expresses the changing colors of the sky from morning to night in its body design. Holding it evokes the feeling of looking up at the sky during a busy day—offering a moment of calm and a renewed, positive mindset, creating a relaxing and soothing product experience.

Key Features of the New Product ■

1. Body Design Reflecting the Sky's Color Transition Throughout the Day

Centered on themes of calmness and serenity, the design captures the sky's transformation across different times of day. A natural, soft gradient blends gentle colors from the upper body down to the white grip, resulting in a lightweight, cohesive design. The single pens come in six variants: 'Seicho (Clear Morning),' 'Hirusagari (Afternoon),' 'Akenesora (Crimson Sky),' 'Tasogare (Twilight),' 'Akera (Bright Sky),' and 'Yofuke (Late Night).' When arranged together, they showcase the evolving colors of the sky from dawn to night.

All pens use black ink, with ball diameters of 0.4mm (only 'Hirusagari' and 'Yofuke') and 0.5mm.

2. Three-Pen Sets Featuring Exclusive Set-Only Designs

In addition to individual pens, two types of 0.5mm three-pen sets featuring exclusive designs are available. The 'Day Time Set'—inspired by the daytime sky—includes 'Seicho,' 'Akenesora,' and the set-exclusive 'Niji (Rainbow).' The 'Night Time Set'—inspired by the night sky—includes 'Tasogare,' 'Akera,' and the set-exclusive 'Houkiboshi (Comet).'

The sets come in glossy, softly rounded packaging, with the back panel designed to be cut out and used as a bookmark.

Features of FLOATUNE ■

1. Comfortable, Floating Writing Sensation

By combining a system that allows ink to flow abundantly with the cushioning effect of special ink, FLOATUNE minimizes friction during ballpoint writing to the greatest extent possible, achieving a floating writing sensation.

● Key Elements Behind the Floating Writing Experience

'Cushion-Infused Ink' that softens contact between metal components

'Overflowing Technology' that smoothly delivers a generous amount of ink

'High-Precision Tip' that optimizes the pathway for special ink to flow smoothly

2. Noiseless Design

With a simple, smooth shape in white and gray, the design eliminates visual clutter, creating a noiseless aesthetic that complements the 'floating writing sensation' and doesn't interfere with thought.
