I have no idea what I use, it is little and I buy the hot temp glue sticks at Walmart. I do know something though.... it sure causes blisters! lol
I have never tried it on foe. I did however try my wood burner on the foe, to melt it together...for all you gals that know how to do that, PLEASE tell!
All I did was burn the crap out of it and man did it stink! Turned it black!
I just bearly touching it to the foe too!
