Renew the sound of your soprano ukulele with this Dunlop string set. Dunlop ukulele strings are made from their patented VSD-7 Polymer material. This plastic polymer guarantees stable intonation and increased string longevity. From its factory in Benicia, California, Dunlop manufactures these string sets by running its machines at a slower pace and producing smaller batches, which allows for greater control over every step of the process. In addition, the set is sealed in a protective bag to keep them fresh and durable. Made in the USA
