Keyboard maker Highground introduced a keyboard in collaboration with Sonic the Hedgehog.
The keyboard is 65% in size and is divided into three types: Sonic Adventure, Greenhill Zone, and Dreamcast. Sonic Adventure is engraved with Sonic and Shadow, Green Hill Zone has a 360-degree section of the stage, and Dreamcast has the body engraved.
The three keyboards are equipped with a TTC speed silver shaft that responds quickly to the characteristics of Sonic, and support hot swapping. The sound-absorbing material for the aluminum reinforcement plate is silicon.
In addition, Sonic Adventure and Green Hill Zone are sold with keycaps in 68-key and 104-key arrangement. In addition, mouse pads with Green Hill Zone and Sonic-related goods are sold.
