It's best to go to an online shop. It's cheap and good. However, if you don't like to buy it in online stores, you can go to a bookstore, preferably a bigger one. If the bookstore doesn't have it, I suggest you go to the educational toy store, and the train station supermarket will also have it. Finally, regarding the price, I suggest you buy something around 20 yuan. It's not necessary if it's too expensive, and it's definitely not possible if it's too cheap. You'd better buy a Rubik's cube with secrets. One more thing, you can't just look at the price. You'd better open the wrapping paper and try it. You can easily hook a layer with your fingers (rotate it 90 degrees). Finally, don't buy a Rubik's cube with pictures, buy a Rubik's cube with colors. The Rubik's Cube I bought is a Rubik's Cube of "Kiki" brand. Very easy to use. Only ten yuan. If there is, you can refer to it. This is not a promotion. . . )
