The experts of Hey Sign bring these practical felt properties to the kitchen and the dining table. Whether you need it to protect your table from a hot pot coasters, or to use under a glass or a plate – the Hey Sign coasters are available in eight sizes and different colours. Both, the felt material and all the Hey Sign products are "Made in Germany" and the finishing of the products is even "Handmade". The used felt is made of 100% pure new wool without additional chemicals or recycled textiles, which is documented by the wool seal of approval.
