Aquila is proud to introduce the Bionylon® , the first eco-friendly synthetic string in the world. These Ukulele strings are made of rounded, smooth Bionylon® monofilaments – a new material discovered by Aquila - that also boasts excellent acoustic and mechanical properties.
Bionylon® is 63%, a plant’s derivate (castor oil); this allows a reduction of more of 50% of carbon dioxide’s emissions in the atmosphere during the polymer- synthesis than the other common Nylons employed for musical strings. Warm and mellow perfomances!
