From your drawer back into production
Empty cartridges are collected worldwide and shipped centrally to our remanufacturing base in Hong Kong. There they are inspected, cleaned and refilled and pass quality control, then resold worldwide — and when they are empty again, they can come back.
Centralised shipping to one Hong Kong base means cartridges are remanufactured close to where they arrive, and finished cartridges ship directly worldwide from Hong Kong.
