These are the strings you need for a standard (also called soprano) ukulele. Notice that the package lists the tuning notes wrong. Soprano uke uses a reentrant tuning: A4-D4-F#4-B4 or a step lower G4-C4-E4-A4. These nylon strings gauges work well for both standard tunings. This isn't the first time we've seen printing errors on Black Diamond strings. They're good strings, but sometimes it seems that they don't proofread their printed material.
The strings are in a seal package for long shelf life. That's good!
