Aluminium cover: environmentally friendly: the world's first hard shell aluminium cover made of organic plastic which is produced purely from renewable raw materials and is not petroleum-based. All packaging components are environmentally friendly made from 100% FSC certified paper and bioplastic plastic. Perfect fit: Krusell Alucover has been specially designed for Apple and Samsung models. Convenience: all functions and ports of your smartphone are fully usable without having to remove it from the case. The shell does not attract dust and does not stick in your pocket such as silicone or rubber covers. It is also ultra light and weighs only 12 grams. The aluminium on the back offers an elegant and extraordinary design. Protection: the exclusive Krusell design not only looks good, but also protects your smartphone from external influences and scratches. The patent-pending snap-on attachment keeps the screen away from flat surfaces while the device is facing down. The Krusell promise: Since 1991 Krusell bags have been setting standards in terms of fit, workmanship and comfort. Every single case is lavishly hand-crafted and quality is constantly checked. Only non-toxic and flawless materials are used to meet the highest standards.
