Detailed botanical illustrations of various mushroom species in warm ochre, cream, and rust tones scatter across a deep graphite black ground in a dense, all-over composition. The naturalistic rendering style recalls vintage mycological studies, with each fungal form rendered with careful attention to cap shape, stem structure, and distinctive features. 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.
