P602 NASBIE, 2 rounds hand gun.

It has a simple method.

The frame-hook.

When the trigger is pulled, 2 rubber bands are released at the same time.

But only the red band is held at the frame-hook.

When the trigger is returned, the red band moves to the trigger-top from the frame-hook by the ramp.

Grip is like an aubergine.

The name NASBIE (Nasubi) means "AUBERGINE" in Japanese.
