HOW IT WORKS
Zero Commitment. 100% On-Demand. We only process refills after the USPS scans your empty cylinders. If you never send them back, you’re never charged again. Simple.

📦 Get Your Label ($0)
Choose your cylinder count and checkout for $0. We’ll email your prepaid return label instantly
-
📦 Ship When Ready
Pack your empty cylinders in any box, attach the label, and drop it at to the carrier. No rush, no deadlines.
-
📦 Scan to Ship
Once USPS scans your box, your card is billed for the refill and we ship your fresh cylinders the same day!
