The article states that this is a portable paper-based Go game.
I found a post on XiaoHongShu that includes all of these pictures below and with the following translated information:
Go is a very popular game in many East Asian countries. However, traditional Go boards still have many problems in terms of manufacturing and portability. For example, the pieces are too heavy to carry and visually impaired players need specially made boards. A lightweight, portable Go board became a market need.
So we created Poppu Go Chess, a lightweight and portable Go board. Using the art of Kirigami sculpture, our design combines the board and the pieces into one and creates a new tactile experience by unfolding a three-dimensional space within the paper. At the same time, Poppu was designed with a strong focus on the visually impaired player’s experience, customizing it for them.
Poppu’s graphics are produced using die-cut and letterpress printing. It is suitable for any kind of paper, ranging from 120-220 grams. The lightweight and portable design makes it perfect for traveling and playing Go anywhere. Poppu is more affordable and less costly than traditional Go boards. The flat design allows for a smoother and relatively quicker manufacturing process.
In the end, we want to invite and encourage more people to get in touch with Go and enjoy this ancient cultural tradition in an easy, relaxing way. Poppu, on the other hand, is a new, portable, relaxing and enjoyable way to experience Go.
