Soprano Ukulele Strings
Soprano strings almost always come in re-entrant tuning. If there is no indication of whether the set is high or low G, it's fairly safe to assume they are high-G.
They will often indicate a tuning either C-tuning (gCEA) or D-tuning (aDF#B). However, which ever size is indicated, the strings will be suitable for the other tuning - there's not a great deal of difference in tension between the two.
