When I first heard about it, I wondered if it is indeed a real product, or merely a type of e.g. cow's hide print - but then, I'm repeating myself, I've yet to see or use one (never liked traditional leather wrap, preferring linen or wrapless, for the usual reasons: slick when dry, sticky when sweaty, plus that discolouring effect). I believe it's justified to discuss material properties and understand why there would be demand in the first place. Speaking of fetus skin, not sure if everyone realizes mother cow's abortion once used to be caused systematically to get the most sought-after "spotless" (= fur-/hairless in addition to non-spliced) calfskin for the production (writing/copying process) of parchment used in the most highly prized medieval manuscripts? I know of no one who does not find this abominable (I did research for an academic paper on the subject at one time, and the mere thought still sends chills down my spine), even so, it makes sense to know why it was done. Also, it's simply a useless venture to ignore the reasons for demand: think of the blue diamond tablet pill that's more or less saved the rhino?
Greetings from Switzerland, David.
