Fifteen hand-tied trout flies are arranged in a neat grid against a pale cream background, each one meticulously detailed with fur, feathers, and thread in shades of brown, black, red, and gold. The composition has the precision and documentation style of a vintage naturalist's reference chart, rendered with fine linework and subtle watercolor washes that capture both the delicate construction and practical purpose of these fishing lures. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
