FASTEN created a stylish refillable cosmetic cream jar that looks amazing, but at the same time is sustainable in so many ways! By using only 1 material, (recycled) PP, for all parts of the product, we prevent any disruption of the recycling process. There is a 70% reduction on materials compared to a standard cream jar, which is an amazing result! By reducing weight in the design and making the refill stackable, there is a significant CO2 reduction realized in transport. By replacing ink with debossing and folding the cardboard instead of gluing, an ultimate sustainable jar is born!
