MIAOU never lets her concentration lapse as she preserves the purity of wine and spirits: her flexible stopper creates an airtight seal that keeps liquids and their bouquet safely inside. What's more, there's scarcely a bottle that MIAOU won't turn into an elegant gift. And she'll even add the finishing touch to rare vinegars and fine oils! Absolutely neutral in taste, MIAOU is also a snap to clean. It is made of elastic silicon material.
