Mitsubishi Uniball, the UK subsidiary of the global Japanese pen and writing utensil brand, made the switch to paper packaging in 2020, eliminating its plastic blister that gave consumers a view of the pens. The company worked with UK packaging company and design house FACER to create its board-to-board blister pack, proving that co-solving can spur plastic-free innovations. Uniball increased its market share in the UK to 38% following the launch, demonstrating not only a consumer demand for innovation, but a new era of design where plastic doesn't have to be the go-to.
