GHS knows that you want your strings to be as fresh as the day they were made. All GHS facilities are environmentally regulated to control temperatures and humidity. Sensitive raw materials and bulk products are further wrapped in protective bags for storage. Coiled strings are placed in string packets that, in independent laboratory tests, have proven to offer the optimum protection from humidity. Concert/Standard guage - Black Nylon.
Comments about GHS H-10 Hawaiian Black Nylon Ukelele Strings:
These strings sound more like what I think a Ukulele sounds like than the expensive white strings that sound more guitar/banjo like. They stay n tune well, last a long time, and are a nice contrast to the uke's top color. You should buy these. (They are also cheap!) :D
