"This Classy Whisky Decanter with lid has all the 3 essential features of a good whisky decanter. 1. It has a tight seal (lid) that doesn't let air enter or escape. 2. It is large enough to decant the whole bottle of scotch, which is typically 1100 ml. 3. The Decanter is lead free, so there is no danger of lead leaching into the whisky over time."
