The ZOS Halo Wine Preserver uses advanced technology to preserve your wine.

A simple yet elegant design makes this wine preserver a delightful addition to your bar. It uses the latest and most advanced technology to preserve opened bottles of wine. An oxygen absorbing cartridge is filled with a specially formulated clay compound, which absorbs 100% of the oxygen in the bottle to deliver wine that’s just as fresh days later as it is when you first open it.
