Gradius and Twinbee items × Konami Bubble Memory System 1985 Arcade machine pcb

1. Gradius cartridge empty metal shell only. Very good condition for age. 2. TwinBee shipping box. ultra rare, this was used to return catridges to Konami for updates. it is in poor condition but still a nice display item. the box protector is included. Note. The cartridge is the complete metal shell but does not contain the game and is empty inside. Thank you.
