These strings are new and unopened 'old' stock, in other words excess inventory,  hence the low price. How 'old' I couldn't say.

The strings are sealed in plastic to guard against corrosion.  The integrity of the packaging has been checked and appears fine.  Therefore they ought to be free from of corrosion and so fit for purpose.  Please note that these are offered at a reduced price as I can't completely rule out the possibility of tarnishing/corrosion.  It is unlikely however given that they are still sealed. 

Manufacturer  Description

With the resurgence of the “Le Hot Jazz” tradition, our Gypsy Jazz Series were designed to satisfy the needs of these faithful practitioners and innovators. These perfectly balanced sets are best suited for the driving percussive rhythm style called “la pompe” and the blistering leads using fast scales, slides and chromatic chords.

Our Gypsy Jazz strings utilize our proprietary Silk & Steel construction. Our high grade silver-plated copper wire is hand-wound over a middle layer of pure Italian silk filament and an inner steel core. Preferred by finger-style Gypsy Jazz guitarists for their soft touch and sweet tone, these strings have less tension than standard steel, bronze or brass wound strings.
