For convenience purposes, we encourage our consumers to return all 4 cylinders at once.
Your cylinders will arrive in a box with a prepaid shipping label attached. Use the packaging from your original order to pack up your used cylinders.
If you lost the box from your original refill order, you can request a new label through the Collect+ site and use any box to send back your empties.
