I bought some 9's and 10's in these, both had a hole punched in the plastic bags and straight out of the pack they were tarnished :(
I've tried a lot of strings over the past 30 years, and while not the worst strings I have seen ( cough... rusty spots and flaws on Ernie Ball's ), tarnished strings always sound flat to me and never last, so I wasn't going to put them on a $1000+ guitar.
While these are probably on par or close to Dean Markley, Gibson, GHS, DR and better than the Ernie Ball's I've used...... Elixer's or D'Addario IMHO are so much better and last weeks not days before they need changing.
The strings themselves look ok, just tarnished. Could be a good product if Thomman can get them vacuum packed.
