Botcon 2011 Toxitron is missing something. Something you saw in the BC11 comic. He's missing his plunger! Now you too can equip Toxitron with his iconic plunger just like in the BC11 comic. The inner portion of the plunger is concaved. Handle has been designed to fit those robots with a 5mm hand hole.
The BC11 Plunger v1 (this one) is 5mm shorter than the BC Plunger v2.
