Founded by industrial designers Amanat Anand and Shubham Issar, SOAPEN makes colorful soap-filled pens that let children draw on their hands before washing them. The New Delhi-raised, Parsons-trained co-founders created the product to make handwashing more engaging and have used it in hygiene-awareness campaigns in India and the Philippines. SOAPEN also offers children’s hygiene-themed products such as a board book and color-matching socks.
