LOL, here's a lovely vision, a plant somewhere in Afghanistan where a bunch of old men with runny noses are filling all those little bottles for shipment throughout the world. Seriously though, gum trag is one of many things that can be used to slick the edges of a leather item. I have had pretty good results with plain H20 and a drill mounted wooden spool, beezwax, saliva, edge-kote etc. comes to mind. It's up to the artist as to what works the best for them I guess. Finished edges definetly give an item that finished look.
