Flexocor currently offers two sets of strings as the original version is phased out and replaced with Flexocore Deluxe.
FLEXOCOR ORIGINAL strings are steel core, insensitive to humidity and temperature changes. They are identifiable by maroon thread with gold spiral at the tailpiece end. *The G and C strings have a high success rate here with most cellists reporting a rich, warm sound. If you are auditionining on Dvorak or the like, you probably want a more powerful string. When these sell out, only the Deluxe will be available
