Inspired by an everyday interaction like doing the dishes, a little more pleasurable, the Finch sensor pump by Umbra incorporates simple, modern forms with subtle design features. Made of molded plastic Finch requires four AAA batteries to operate (not included) and can hold 10 ounces (295 ml) of soap or hand sanitizer. Finch has a wide opening at the top for easy refills and a low soap indicator light that notifies you when it is empty. Has a small footprint on the counter top as it measures 3-3/4 inches in diameter and is 7-3/4 inches tall. Designed by Alan Wisniewski for Umbra- original, modern, casual, functional and affordable design for the home.
