Amazon purchases are one-time orders and do not sign you up for the Aarke CO2 Cylinder Loop. To begin your subscription please visit our Cylinder Loop page.
For orders that were the exchange box only, your label will arrive affixed to the box already.
For all other orders through aarke.us, please login to your account by clicking the person icon on the top right hand of aarke.us. After logging in, select Manage Subscriptions. Please select your most recent order and under 'Exchange History' click Download under the column 'Download Return Label'. This should begin an immediate download for your label. If the download is not being triggered, please try using a different browser or ensuring downloads from aarke.us are allowed on your current browser.
