Leather Flask - That's What She Said Our Leather Wrapped flasks are fun, functional, gift-able, and good looking. We wrap an 8 ounce stainless steel flask (your choice copper coated or matte silver) with a leather sleeve that's hand stitched on the back. The flask has a hinged top attached. The leather is earthy, a perfect match stamped with one of our stock designs or create a custom design.
