Duallok packaging


We wanted to use zero plastic but when we saw what kids can do to a cardboard box we realised it was going to be almost impossible.

Instead, we've tried to use as little as possible and 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 after use.

The tear-resistant laminate is 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.
