Our Stainless steel flasks are wrapped in vegetable tanned leather from Wickett & Craig in Curwensville, Pennsylvania. We hand carve or laser etch each dye cut flask, and treat them with penetrating oil dye and water resistant sealer before stitching them with artificial sinew, we then cement the leather to the flask for maximum durability. This Light brown flask measures 4" wide by 4 1/2" tall, and holds 6 oz. Etched with a 1912 Map of Toronto, Ontario.
