(CNN) - Nintendo is going old school and old-fashioned.
The Japan-based company has a new line of low-tech accessories for its Switch and Joy-Con controllers.
The items are made of cardboard sheets.
One is a cardboard piano that holds a console and controllers. Musical notes can be heard from the console when the keys are played.
Another kit lets users create an interactive robot suit, complete with straps for a kid's hands and feet.
These cardboard products, called "Toy-Cons," will be available in April.
