Otto automatic soap dispenser by Umbra was designed with a soft inviting form that makes automatic pump technology more approachable. With a gentle taper at the neck, hands can comfortably cup outgoing liquid without having to touch a thing. Otto's sleek profile and soft metallic nickel finish with black accents blend with virtually any kitchen or bathroom decor style. Great for kids and adults alike, the hands-free operation reduces the spread of germs. Use with dish soap, liquid hand soap, or hand sanitizer. Otto dispenses a fixed amount-not too much, not too little-helping to reduce waste and save on supply costs. The window on the front provides visibility to liquid levels. Otto operates on four AAA batteries (not included), measures 8-3/4-inch high by 4-1/4-inch long by 3-3/4-inch wide, and holds 9 fluid ounces (266 ML). Designed by Dennis Cheng for Umbra-the worldwide leader in casual, contemporary and affordable design for the home.
