Rodaviss Stopper – Solid Bottom 45/50
A Rodaviss Stopper will help prevent your glassware from getting stuck together.
A black plastic ring sits below the glass protrusion on the dome; When the stopper is unscrewed, the ring pushes up against the protruding glass. This creates even pressure, preventing your glass from getting stuck.
