Keep your opened wine fresh for up to a week! Simply place the Vacu-Pump over the reusable Vacu-Stopper and pump. The pump removes virtually all the air from the bottle, preventing spoliage from oxidation. A special vacuum indicator “clicks” when the maximum vacuum level is reached. This gift set includes one Stainless Steel Vacu-Pump and two reusable Vacu- Stoppers. Also included are two wine server crystals that allow for perfect, non-drip pouring every time. Ideal gift for the wine lover in your life.
