These shrink bands fit the BIG tubes, not the regular, not the bigger, just the BIG TUBES.
These shrink bands are ready to slide over the tube for shrinking with a heat gun. We set the heat gun on medium-high and do an initial shrink around the tube, and then we follow up with the hot air blowing the tube across the counter. As the tube rolls away, all of the shrink band areas are exposed for even shrinking.
