I have the EGO-C. Clearomizers are the Vision. Does anyone know where I can get the white rubber like grommets that go around the bottom of the Cartomizer that seals the Clearomizer? OR..... OR.... My soon to be step-son has braces. each night he has to put very small bands in his mouth. They are like rubber bands. Would these work as a patch until I can get the grommets or Cartomizer? They are about the same size as the grommets. but totally different materials.
