After the great success of our New Nylgut Ukulele strings, we are introducing the SUPER NYLGUT strings, the ultimate improved version of our world famous Nylgut & New Nylgut.
SUPER NYLGUT strings -juxtapose with the traditional New Nylgut ones - have a natural pearl color and a very smooth surface to the touch that make it almost like wax.
