A dense collection of illustrated mushrooms in varying shapes, sizes, and colors fills a black background, each specimen labeled with its common name in small lettering. The palette ranges from warm oranges and yellows to cool purples and blues, with playful character-like faces on many fungi, creating a whimsical yet informative mycology chart rendered in soft, rounded illustration style. 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.
