A dense scientific study of insects rendered in warm sepia tones displays dozens of specimens arranged in a radial composition around a central winged insect. Fine ink lines and meticulous detail work create an encyclopedic quality, with handwritten labels and geometric construction marks suggesting the methodical observation of natural history illustration. 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.
