Sorry, we do not!
“Mylar Balloon” materials are NOT made out of Mylar® plastic film. They are made of coated Nylon film that is specially designed to hold helium gas and also be heat-sealable to itself. “Mylar Balloons” are not made of Mylar® brand, or Polyester Film, or DuraLar, or Acetate. Sorry we can’t help with this one.
