Worth Ukulele strings:

Worth Ukulele strings are made in Japan, and as you would expect, are incredibly precise and clear. These strings are as close as you can get to perfect. If ever we had a ukulele with an intonation issue, we would always put a set of Worths on, as this would tell us straight away whether it was a problem with the old strings, or with the ukulele. Worth ukulele strings are made from fluoro carbon, which has a higher mass than conventional nylon, for a clearer tone and more precise intonation. Worth offer a range of sizes of the ukulele strings for soprano, concert, tenor and baritone ukuleles.

There are no wound strings in any set of Worth ukulele strings. The benefits of this are that, with all the strings being of the same (fluoro carbon) material, the tone and volume across the 4 strings is more even balanced. Sometimes a wound string can overpower other nylon strings. The slight downside of sets without wound strings is that a low string, a Low G for example, made from all fluoro carbon, can often be quite thick. Occasionally this may mean the string doesn't sit comfortable in the nut slot (which was probably originally made for a thinner string) and you may have to make some adjustments.

Finally, Worth sell their strings in double length sets. This means each string is twice the length you will require, so cut the strings in half to give you a second set.
