【HMM】Egg Shell Ballpoint

"The Aesthetic Experiment of Circular Life This is a gentle experiment in material circulation. In collaboration with ""Tainan Egg,"" HMM has repurposed discarded eggshells into a 100% biodegradable pen body. The creative journey was a rigorous test of endurance, balancing environmental responsibility with the structural integrity required for daily use. Visually, we’ve translated biological imagery into a minimalist design: the egg-shaped silhouette paired with a warm brass tip evokes the image of a yolk, turning a writing tool into a soulful symbol of rebirth and craftsmanship. Unique Geometry Tailored for the Hand The Egg Shell Pen is as ergonomic as it is visually striking. Its unique ovoid geometry is thoughtfully designed to fit the hand: the blunt end rests naturally against the purl of the thumb, while the tapered tip provides a comfortable grip for the index finger. Inside, it houses a high-quality German-made Parker refill for easy replacement and long-term use. Featuring a silky-smooth twist mechanism, every turn offers a tactile satisfaction that complements its superior writing performance—a refined companion for a sustainable lifestyle. 設計特點 Crafted from recycled eggshell powder blended with biodegradable PBAT, this pen is designed to fully decompose—100% across the entire body. Its form echoes the natural curve of an egg, while the gently rounded ends are shaped to fit comfortably between the thumb web and fingertips, offering a smooth and ergonomic writing experience. 循環說明 Through a chance encounter, HMM learned that Tainan Egg generate a significant amount of eggshell waste each day while producing liquid egg products. This sparked a question: beyond routine disposal, could these discarded shells be given a second life? What followed was an extended period of material experimentation and testing. After numerous trials, an optimal formulation was developed—one that balances durability in everyday use with full biodegradability. The result is a distinctive pen made with recycled eggshells, combining sustainability with a memorable, egg-inspired design."
