Oh dear...read again please...
I could give a **** about websites. Still do not see the silk wrap LENGTH....
I did read your post. You talked about wanting to have all the info on the package. Good luck with that.
By the way, why would you need to know the "silk wrap length"? The important thing to know is the actual winding length of the strings so you can make sure they're the right length to fit the bass properly.
