Mercy Leather Works is brilliant little etsy shop owned by Rusty Zylstra of Grand Rapids, Michigan. He says “My goal with designing bags is to make something that is built to last. I enjoy making practical items for people to use in there daily lives” Reading about all that goes into each bag is a joy—waterproofed, padded adjustable straps, tons of extra pockets and care. Rusty can also make anything else you can think of custom, from toe straps to lock sleeves. Shake it Rusty.
