Here's the blurb: "Whether you live for a thundering thump, a rhythmic slap or an artfully woven line, Dean Markley Blue Steel bass strings will get you there. Cryogenically frozen with a blast of liquid nitrogen, Blue Steel strings deliver massive tone, resonance and longevity. These babies are built to last! Try Blue Steel Stainless Steel bass strings for a brilliant punchy tone."
Strings are all sealed, no need for them myself as I don't play 4 string.
