Fine and her fellow cofounder Janet Lieberman created the Fin to help "close the pleasure gap" for women by enhancing natural touching. The USB-rechargeable device has a three-speed motor inside and is made of medical-grade silicone. Designed to be "small, simple and powerful," it can be held between one's fingers in multiple positions (tips of the fingers, along the palm, back of the fingers).

In contrast to their previous Eva product, Fin's "hands-on" nature is intended to bring partners closer together, while addressing many women's need for clitoral stimulation to reach orgasm.

Delivery is estimated to begin in December, and preordering via Kickstarter is available for $60, a discount from the planned $75 retail price.
