The token contains all important information about the character and makes them recognizable to everyone else.
Enter the data, the simulator will show you what your personal token will look like. Then, to obtain it, you can click the "copy" button — and paste the copied data into the basket. Alternatively, you can go to the store and create the token there (you can even make two identical ones, and also choose your own inscription or image on the back). Don't delay.
