With thousands of large red cylinders traveling to recipients across the globe, RedShip has done what countless doctors haven't been able to do: cure homesickness. The company's signature care packages deliver comforting snacks, items, and personalized cards from the sender. The gifts are collected for their broad appeal, meaning that they'll brighten the day of a college student just as much as that of a sleepaway camper or a soldier.

Customers choose from different package sizes and themes—there's a healthy package, for example, as well as a seasonal Christmas one with a miniature tree—or sign up for a monthly package subscription. The cylinders are then shipped off to their destination laden with treats such as gummy bears and laundry bags for when the giftee hugs the gummy bears too hard and stains their shirt.
