Rengo is said to be cardboard maker for Nintendo Switch Labo

Japan’s Rengo Co is supplying cardboard for the Nintendo Co Switch accessories that will go on sale later this month, people familiar with the matter said. 

The Osaka-based manufacturer of processed paper and corrugated packaging is one of several companies in the supply chain contributing to Nintendo Labo, said the people, asking not to be identified because the matter is private. The cardboard sheets pop out and fold into everything from motorbike handles to fishing rods and a miniature piano.
