Ostrealis

A security seal made from recycled oyster shells!
Sustainable packaging begins with the use of existing materials, already extracted and already part of other production cycles. By transforming these by-products rather than sourcing new raw materials, we create solutions that are more circular and respectful of the environment.
The result is a label that feels natural, textured, and alive, carrying its own story – a material of the future for responsible brands.

Technical Features
• Material: composite, made of half oyster shells and half bio-sourced polymer (plant-based, petroleum-free).
• Available shades: several natural tones, varying according to the origin and treatment of the shells, with the option to develop custom colours.
• Appearance: mineral, slightly grainy, rigid.
• Finishes: matte, varnished, polished.
• Format: fully customisable (shapes, dimensions, moulding).

Originally developed as a seal, this material lends itself to many more applications: medallion for champagne bottles, ornament hung around a perfume bottle neck, premium detail on high-end candles, jewellery accessory, authenticity marker for limited editions, or even a storytelling element inside a presentation box.
