Crownes Chess, a chess set launched by ETHO and DesignNest, has reduced the storage space of chess pieces and chessboards by 75%. The design team used the concept of Russian dolls to determine the size according to the importance of each chess piece. Pawns are the smallest, and kings and queens are the largest. When storing, they can be nested into two piles of queens and kings according to the size of the chess pieces, with eight chess pieces in each pile), and magnetic force is used to ensure that the two piles of chess pieces are firmly together. , put it into a cylindrical storage box. Each storage box can hold sixteen chess pieces, so there are two storage boxes for the attacking and defending chess pieces. The chessboard that takes up the most space is made of leather or silicone. It is soft and easy to roll. It is just big enough to wrap two storage boxes together and roll them up. Whether it is carried in a bag or fixed in a It doesn't take up any space in the cupboard.

When players want to start playing chess, the process of opening the chessboard and placing the chess pieces is also very interesting, especially when the players push it gently and the chessboard slowly spreads out along the force of the storage box, which is quite impressive. The flavor is there, but this is not really a battle of life and death, but a showdown on the chessboard.
