Empty Cylinder Returns

Ready to refill? Select the number of empty cylinders you have ready to ship. We will instantly email you a prepaid USPS return label for $0.00 today.

How it works:

  1. Request: Checkout for $0 to receive your label via email
  2. Ship: Pack empties in any box and drop at the Post Office.
  3. Scan-to-Ship: We only bill and ship your fresh CO2 once USPS scans your box.

No subscriptions. No hidden fees. Just the easiest way to keep your bubbles flowing.
