What do we need to do once the containers are full and we need replacements?

Ensure the containers are securely locked (once the containers have been locked they cannot be reopened) pack the containers back into your shipping box the same way you received them. 8 containers for the 2 litre size and 4 containers for the 4 litre size. Place the peel and stick return shipping label you received at time on the lid of shipment of your container. Fax us your Service Request Form and we take care of the rest.
