A brown and white guinea pig sits centered against a cream background, its round body rendered in warm watercolor tones with careful attention to fur texture and coloring. Thin lines radiate outward from the animal, each labeled with anatomical terms that map the creature's features from nose to rear end, creating an educational yet whimsical diagram that treats this small pet as a subject worthy of scientific study. 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.
