Protection: Metal is completely opaque, offering the best protection against photo-oxidation (light damage), compared to glass.
Sustainability: Tins are lightweight, reducing the carbon footprint of transport from Sicily to Prague.
Refill Safety: While glass is excellent for home storage, professional-grade coated metal tins are a standard for preserving quality in larger volumes.
