Adding this most important one to the Plarail collection.
These cigarette holders and filters are 40 yen each, and they are crucial to any friction power motor.
Reason is that these rubber o-rings are a perfect fit to the motor's friction wheel.
The reason why choose this over normal water faucet o-rings is that cigarette filters are found everywhere in Japan and tool shops are not as close to a hometown area.
That is the cheapest, most common, and most important "alternative" Plarail in my collection.
