The innovative ?Rock? design at the bottom of the crystal glass creates a natural liquid motion, increasing the nosing of aromas. The stainless steel chilling balls outlast traditional ice cubes, while the shape of the glass makes swirling easy, without spilling. A slight hand movement rolls the chilling ball around the ?Rock? evenly and cools your favorite scotch, whiskey or liquor to perfection.DuraShield TM Titanium reinforced?100% Lead-free crystal for excellent durability, clarity & eleganceDesigned to enhance the appearance of whiskiesPattern is etched by hand & then polishedPattern provides a secure grip when pouringCrystal stopper helps to seal in freshness & aromaCapacity:?Decanter: 1L (35oz.),?Glasses: 400mL (13.5oz.) eachDimensions: Decanter with stopper: 26cm(H) x 12.8cm(?), Glasses: 8.2cm(H) x 9.5cm(?), Chilling balls: 4.3cm(?), Chilling ball bases: 2.3cm(H) x 6cm(?), Tongs: 14cm(H) x 2.5cm(W)Handmade & dishwasher safeCare: Wash before u
