This model reproduces the internal structure of the keyboard keys of the Olivetti PC128S and Thomson MO6. Specifically, it replicates the fastening mechanism located beneath the keys, including the side wings that ensure their stability. However, over time, these labels tend to deteriorate or break, resulting in abnormal key drop and excessive lateral movement. Although the keys can still be used, the lack of sufficient support can compromise their ergonomics, making typing less comfortable.
