If you open the BOL zipper, the closure on the inner ball can no longer be found / visible. Apparently it has slipped over time. I can't let the air out.Updated a year ago
Try to relieve the ball's internal pressure by placing the ball in a cooler room, such as a room. B. basement or garage, for about 3-4 hours. After that, the internal pressure should be reduced enough for you to be able to reach and open the closure.
The zipper cannot be closed.
Normally your BOL is full before the zipper can no longer be closed. Please release some air and try zipping up again. Tip: press the inner ball in front of the slider with your thumb to make it easier to close.
