SafeTite Sealing Discs are manufactured by Qualatex to make sealing latex balloons easy. Unfortunately, Qualatex has discontinued manufacturing this product.
How it works
Once the balloon is inflated, stretch the neck of the balloon into the slots on the disc. Balloons sealed with these discs are reusable by simply unwrapping the neck of the balloon from the discs.
SafeTite Sealing Discs work best with 18-inch latex balloons and were available in clear and green. SafeTite Sealing Discs were also available with or without ribbon.
