Lots of stuff posted as to "what looks like ivory and is cheaper" try doinf a search, I know someone may come up with a "link" (not me,out of MY job classification)
anyway, Tru Ivory from Bar S Grips out in Everett,Wa, and our own Cary ( here on the Forum) we've use over the years, so I can personnaly vouch for and testify, they are BOTH excellent choices, and loved them all...Tru Ivory was "pour,molded" polymers, and Cary's used in this case "Holly Wood" and BOTH look like ivory and are not "cheap" by any means BUT far less costly than REAL ivory, like 20-30% of the cost of REAL ivory......most of the "fake" ivory folks "see" today are 'polymers (plastic) and look like that, "plastic", too white...........some of the early" polymer" and mixed or what some called "bonded ivory" used real ivory 'dust, power in the mix..........do not see them often and most of the ones we've some across again, too white, NO grain............good luck, and scan the want ads, may find a pair of older, yellowed? Ajax or Eagles, there are lots around...........
