Collection: Mustard Beetle Water Bottles

Take a little field guide wherever you go. Mustard Beetle’s illustrated water bottles bring artist and naturalist Elizabeth Jean Younce’s richly detailed observations of the natural world to durable, everyday Nalgenes.

From hummingbirds and native plants to landscapes and wildlife, each design begins with Elizabeth’s curiosity about the living world and turns it into functional art made for trails, road trips, everyday errands, and wherever else the day leads.

Mustard Beetle is a woman-owned creative studio led by illustrator, printmaker, and naturalist Elizabeth Jean Younce. Her work blends field notes, natural science, and storytelling with a deep respect for the places and creatures that inspire it.
