The larger bands for engraving have a simple ribbed design except for the spot left blank. It's more uptown than stamping a personalization into the celluloid. The other one I have is also a Balance, but with golden brown striations. Since these are middle twist pencils, the band gives you a nice grip-spot when advancing the lead.
But that is not the only thing different about the "ebonized pearl" pencil--its slightly tooth-marked top is slant-cut, not pointed.
Like no other Balance I have seen so far.
Did you notice that the tops and tips of these two are solid black? They must only have made narrow strips of this pearl. What a pity, when it's so pretty!
