Is this the second time I've viewed your post? Perhaps and if so, at first I couldn't wrap my mind around the idea that anyone would use horseshoe nails for hog nose rings. And also if so, this time I noticed and went to the datamp entry — and lo and behold, they were designed for horseshoe nails as well as "normal" hog rings! Well bless my buttons and similar entries! Needless to say, I was surprised. I've never used hog rings, I'm guessing my pigs were so pleased with the size of their pens (excessively large, according to neighbors) that they never tried to root out. And now that I've rambled on, thanks very much for your listing, even though I'm not that keen to own one. Sorry.
