Nevas Water - closure for water bottle

For a consistent perlage - the original NEVAS Water closure. In keeping with the design of the bottle, these closures allow the fine carbon dioxide to retain its full power over the long term. In addition, due to the flat design of the cap, the bottle hardly gains any height and can therefore be stored in conventional cooling devices without any problems. The closure fits both bottle sizes 0.75l and 1.5l.
