These are 180cm x 140 cm.
Large enough for 25 FULLY inflated 30cm balloons. That is double a Hi Float bag capacity. We use these to pull over the ends of a piece of garland, for delivering loose balloons for ceiling etc, and for large bouquets and other delivery pieces that don’t fit in our smaller blue bags.
Also the best bag for loading balloons into a drop net – shove the full bag into the net and then just pull the bag back out leaving the balloons behind.
