I have purchased quite a bit from Masecraft supply. I have tried both the rod for beauty rings around the wrap and the slab for inlays. It is a bit softer than juma, but looks a lot like traditional ivory, grain and all. I actually like to work with it, it glues well, polishes nice, takes sealer and clear well, and turns down nicely.
I would recommend it as an ivory substitute.p for looks. I haven't tried it out as a ferrule or anything, but did with a joint collar replacement out of it...it seemed durable with a good feel...replacing an implex thing.
