The first linear brick of its kind in the market designed and manufactured by Petersen. It is a 100% handmade product using unique waterstruck techniques. The K23 has a rich red base colour with subtle lighter tonal nuances across the surface . It is a through colour product with surface creasing synonymous with the handmade manufacturing process.
