Bionylon® strings are made using a recently discovered bio-plastic derived from vegetables. 63% of Bionylon® is made of castor oil; this allows a reduction of more than 30% of carbon dioxide’s emissions in the atmosphere during the polymer-synthesis, as compared to other common Nylons employed for musical strings. Excellent acoustic and mechanical properties, warm and mellow performances.
Ideal for pedal harpists seeking a greener alternative without compromising on tone, this single string produces a clean, expressive sound with excellent stability. It’s part of a new generation of sustainable string-making, reflecting a modern awareness fused with artisanal precision. The Bionylon® string represents more than just a functional component—it’s a step toward conscious musicianship.

Our strings are designed for players of all genres and experience levels. Whether you are a passionate beginner or an accomplished virtuoso, Sipario has the perfect string for you.
