Leather-Bound

RD: Oh, hey, I thought this book felt different! Turns out it’s made of leather!

TS: However, even nowadays, there are places that will make leather bindings on request, or even re-bind a book for you!
(RD: Neat!)

SS: Hahaha, you scaredy-cats!

TS: Uh, that book’s made with horse leather…
