All the violin is made only with jeans cloth. Looks nice and play very good. I have the patent for all stringed musical instruments which are made from soft and flexible materials. (paper, cloth, synthetic leather, plastic, etc), and mixing of these materials. I prepare and other strings musical instruments and i interest to working and cooperation with galleries and making exhibitions. In these galleries exhibitions will be make a musical events with the musical instruments that exist in the exhibition. All this violins is the first i make and is a prototype. Is a full playable ...but have 1 or 2 small problem in some points. For this reason this violins is only for the exhibition and shows and not for a sold. If someone wants to buy one, would I make a new similar in appearance but not the same . All the instruments is unique. If someone wants something special, can send me and the material that wants to build a musical instrument.
