The portable (3 lb/1.4 kg) tool to size latex balloons at any increment from 1.5″ to 36″ (4 cm to 91 cm). The new metal ruler base can be folded for compact use (as in the top two pictures above), or extended for larger jobs (see bottom two photos). Pole extenders are included for use with jumbo balloons.
With a quick turn of a pole, the feet slide to create any size template. To use, inflate a balloon with air or helium, then let out gas until the balloon diameter matches the template.
