A dense collection of hand-drawn butterflies and moths in browns, golds, blacks, and soft blues fills this cream-colored naturalist chart, each specimen meticulously rendered with wings spread or folded in careful scientific arrangement. The composition balances organic variety with systematic precision, creating a catalog of delicate insects that feels both educational and contemplative, with faded text labels anchoring the studied elegance of each form. 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.
