I've been strop shopping off and on for a few months, and came across this: "Jemico Dovo German Razor Strop 23 inch Rindleder Leather & Canvas." Jemico DOVO German Razor Strop 23" Rindleder Leather & Canvas - Knifecenter.com

My question is, what exactly is "Rindleder?" What I get in a search is that "leder" is German for leather or chamois.

Is this a good strop?
