Only remove the small outer screw cap.

Removal of the whole cap may result in the small clear valve seal to drop out.

This clear valve is needed for the bags to be used correctly.

Only the outer cap should be unscrewed and the protective seal then automatically closes the valve when you remove the vacuum nozzle.

Please do not open the package/box with sharp knives in order to avoid damage.

We suggest opening the package/box carefully with scissors or hands.
