The cipher wheel is one of three Caesar ciphers introduced in Chapter 1 of the CryptoClub: Cryptography & Mathematics curriculum.
To assemble the cipher wheels, it is recommended to fasten the paper pieces together with a brad (two-pronged paper fastener). The paper fasteners are not included in the pack.
