Fowlers Vacola Snap-on Caps have been designed for easy, airtight storage after bottled preserves have been opened but not consumed in their entirety.
Snap On Caps transform preserving bottles into storage jars ‘in a snap’, so that Fowlers Vacola bottles can be used all year ‘round. They are moisture-proof and airtight and will guard against ants.

I had no trouble "snapping on" the lids, but when it came time to remove the lid, I could not. It was there to stay. I handed over this to the male of the house, who also had great difficulty removing it. Not a very good product if a woman cannot remove the lid.
