Limited Subaltern Cork Slipmats are now available with a custom design by Berlin based artist The Krank. These slipmats are made for the audiophiles and are ideal for listening and sampling purposes – the cork provides a richer and higher quality sound by adhering closely to the vinyl record, suppressing the arising resonances. *All cork mats are made from natural products. They have been produced based on sustainable Portuguese forest management and in accordance with environmental norm standards – NP EN ISO 14001
