A grid of orange butterflies with black-striped wing tips floats across a white ground, each specimen rendered with careful detail and symmetry. The scientific Latin name "Mesena margaretta" repeats in warm rust text beneath the insects, creating a naturalist's study that balances scientific precision with delicate 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.
