Bought a dozen packs of strings $40

[Robert****]

I'm not sure who makes them but I can tell you that they have been more consistently good than the d'addarios I've used over the years. I've been using them for probably the last 15 years and may have broken 1 or 2 strings. No wobbles or ball end or wrapping issues at all.

So what's the secret brand and where do you buy them?
