I just had my Juliet JB0XXXXX tuned, new lenses installed and ready to wear or sell. Most likely wear cause i still love the look of them lol. Anyway I just read about hammerstems being more rare. Mine are hammerstems but wouldn't all of the JBxxxxxx be that style? And they are referring to other sets of serial numbers? Sry for the newbie questions. Is there anyway to put new foam in the old Xmetal case?
