Modelling balloons (also called Long balloons or twisting balloons or balloon animals – or in their professional name “260 balloons”)
These are the long balloons that we use to make balloon animals with (balloon dog / balloon sword etc’).
These balloons are also made of latex, which is the resin of the rubber tree and is biodegradable. Although most of the people know only one size of modelling balloons, actually, there are 4 major sizes of modelling balloons. These sizes differ from each other in their diameter (their thickness). Their length is more or less equal.
Modelling balloons are marked using the following name convention: Width (diameter in inches) & length (in inches).
For example, 260 balloons are 2 inches diameter & 60 inches long.
260 balloons also have two thicker brothers: 350 (or 360) balloons, and 660 (or 646) balloons. They also have one thinner brother (160 balloon). Why are they 2 names for each larger modelling balloon? Because Qualatex manufacture this balloon 50 inches or 46 inches long, while Sempertex or Betallic manufacture this balloon 60 inches long.
