This is our standard coil bobbin (without copper wire) which is used to form all of our coils. It measures approximately 31mm x 41mm and is approximately 40mm long. It can be used to make your own pop-jet or slingshot coil as well as the backbox coils in an electro-mechanical pinball.
Please note that this is a standard sized coil bobbin, not suitable as a flipper coil.
