We all know that tomorrow’s packaging must be sustainable.
But how can we innovate without drawing further on natural resources? By giving new life to what already exists.
That’s the principle behind by-products: materials already extracted and already used in other production cycles, now repurposed within a circular logic. A different way of creating: more respectful, more regenerative, and not extractive.
The result? A naturally textured finish – mineral, raw yet vibrant – that evokes the sea and tells a distinctive story. In our opinion, this is one of the materials of the future for brands committed to eco-responsibility.
Technical features
• Material: composite made of 50% oyster shells and 50% bio-based polymer (plant-derived, petroleum-free)
• Colours: several natural shades depending on the origin and treatment of the shells, with custom colour development possible
• Look & feel: mineral, lightly grained, rigid
• Finishes: matte, lacquered, or polished
• Format: fully customisable (shape, dimensions, moulding)
Applications & inspiration
Ostrealis is both sustainable and full of narrative potential, suiting a wide range of uses.
We’ve prototyped it as a seal for the watchmaking sector, but many other applications are possible:
• A medallion for champagne bottles, where its marine and mineral texture evokes earth, chalk and deep cellars...
• A hanging tag for perfumes bottles – like a precious fragment from the sea, adding depth to the sensory experience
• A medallion on the ribbon of high-end candles, where the warmth of the flame meets the freshness of a mineral material
• A jewellery-like pendant or accessory – for brands that care about storytelling, down to the last detail
• A mark of authenticity for limited editions (cosmetics, spirits, art objects…)
• A storytelling object for display in gift boxes or presentation cases
