P603 TOMALIANSE, It has a non-burst mechanism.
It is characterized by a needle-hook.
Loaded 2 rubber bands (green and red).
When the trigger is pulled, 2 rubber bands are released at the same time.
But red is held by the needle-hook.
When it is returned, the red band moves to trigger-top from the needle-hook.
Next the trigger is pulled, the red band is released.
The needle-hook is made of a toothpick.
TOMALIANSE (Toma-lyan-se) means "PLEASE HOLD" or "Let's HOLD" in Japanese.
