We wanted our solution to use zero plastic. But when we saw what kids can do to a cardboard box we realised that this was going to be impossible.

Instead our strategy has been to use as little as possible, and to make what we do use, easy to recycle.

The construction is predominantly cardboard, which comes from FSC certified, responsible sources.

The (PP) locking tab includes a code for recycling and is easily removed, with clear guidance printed inside the box.

The tear-resistant laminate is ultra-thin at 1/1000” (thinner than a human hair) and is easily separated during recycling.

Our first job was to protect kids, our second is to protect the environment. We aren't perfect yet, but we care and we will keep pushing.
