This is a new, unopened item. I am selling it because I have stopped the model hobby. Ultra-small LED lamps: Red x1, Blue x2 Ultra-small battery case with switch Extension harness 30cm Thrusters x3 Gem dome x2 Rivets x4 SP plate Please check the sizes of the thrusters, rivets, etc. in the photos. The lamps and switch are new and unopened, but I have not tested their operation, so please understand if there are any defects. I will wrap it in bubble wrap and ship it via Takkyubin Compact.
