Custom made 3x2 inch acrylic double sided keychain with any SEGA system and game art of your choosing, the ones in the picture are just examples, not the only options available.  Just pick how many you would like and add the game name and console in the message to seller note.  I will default to standard US release retail art but I am happy to do any region you would like, feel free to reach out to me with any questions or custom requests, there is no price change for orders wanting alterations.  Ships fast and free, thanks for looking.
