Samples of 10 gram Kaysam balloons purchased in June of 2003 were compared to samples of 10 gram Totex balloons obtained from Kaymont a US distributor for Totex.
The balloon necks were flattened and the with measured with a caliper. The sample balloons were then fitted to a standard U.S. Specification 10 gram Pilot Balloon Nozzle.
