Two guys..

CUPPOW
from Massachusetts took a canning jar and designed a leak free lid to turn an everyday glass into a travel mug. It’s called the CUPPOW, an inexpensive, durable and super easy to clean alternative to the paper cup and plastic lid or the typical travel mug options. The CUPPOW is BPA free, 100% recyclable and made in the USA. The founders, Joshua Resnikoff and Aaron Panone both use the product, a sign it does what it claims. A good sign indeed.
