CK Recycle Envelope - UK Royal Mail

The Crazy Kangaroo Recycle Envelope makes returning your used ink cartridges simple, free, and environmentally responsible. Addressed and ready to use, it works with Royal Mail's freepost service so there's no postage cost to you — just pop your spent HP or Canon cartridges inside, seal it up, and drop it at your nearest post box or Post Office.

Keeping empty cartridges out of landfill has never been easier. Rather than letting used ink cartridges pile up in a drawer, this envelope gives you a straightforward way to send them back for proper recycling — a small step that adds up to a meaningful reduction in plastic waste over time.

Ideal for home users and small offices alike, the envelope is lightweight, robust enough to protect its contents in transit, and compatible with standard HP and Canon inkjet cartridges. If you regularly print at home, keeping a few of these envelopes to hand means recycling becomes a natural part of your routine rather than an afterthought.
