The Liquor Perfection Collection comprises a spiral-shaped decanter and a liquor purifier, both made of tin. It is a particular quality of tin that it can remove the bitterness from wine, whisky, sake and other alcoholic beverages. Both utensils fit in all kinds of glassware and decanters. The spiral is placed on top of a glass decanter, like a lid, to purify wine poured through it, whereas the purifier serves to stir liquors in a glass.
