A street map of Boston overlays the city's neighborhoods and waterways with a gradient of warm yellows and oranges at the top transitioning through deep magentas and purples to cool blues at the bottom. The geometric street grid and organic curves of the coastline merge with the watercolor washes, creating a layered effect where cartography meets fluid abstraction. 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.
