Raw coasters from the Danish brand Aida are a lovely design from the unfussy and naturalistic Scandinavian-inspired Raw collection. The coasters, in a pack of 6, are made of recycled leather and natural rubber, creating a natural and practical touch for any table setting. The material is excellent at resisting dirt and liquids, but is vulnerable to hot surfaces such as cooking pans. They are easy to maintain - simply wipe your placemats with a damp cloth and a small amount of mild detergent to clean off spills and keep them looking their best.
