Frequently Asked Questions


Q: What is Vessel?

A: Vessel is a free library of stainless steel to-go mugs--think of Citi Bike but for to-go mugs. You sign up and begin using our Vessel mugs instead of paper cups. You take it with you throughout your day and eventually return it at a participating cafe or drop box.

Q: Why are we doing this?

A: Contrary to popular thought, paper coffee cups are not recyclable! This is because each cup contains a thin plastic lining that is too expensive to remove. So each time you purchase a beverage to go, that cup eventually finds its way to a landfill. We believe we can do better, making it easy and stylish to take sustainability into our own hands.

Q: Where can I find Vessel participating cafes and drop boxes?

A: See our Locations page here! We have a list and an interactive map of our participating cafes and drop boxes. 

Q: Where do I return the mug?

A: Any participating location here! Also, see above.

Q: How much does it cost?

A: Nothing! There is no charge to participate in the program, however if you lose a mug we will charge a small fee (this is why we take credit card information).

Q: What happens if I lose a Vessel mug?

A: We will charge a $15 fee for all lost Vessel mugs, and $2 for all lost mug tops.

Q: How long can I keep a Vessel mug for?

A: Once you register and check out a Vessel mug you can keep it for up to 5 days before returning it to a participating location. 

Q: Can I buy a Vessel mug?

A: Nope, just like a library book, it’s meant to remain in the commons.
