Fifteen hand-tied trout flies arranged in a precise grid display rows of delicate fishing lures with feathered wings, fur bodies, and curved hooks rendered in muted browns, blacks, creams, and subtle touches of red and gold. The pale cream ground and meticulous craftsmanship evoke a naturalist's specimen collection, capturing both the technical precision and organic beauty of Victorian-era fly-tying artistry. 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.
