Villeroy and Boch La Davina Tumblers are an elegant curved shaped tumbler The La Davinia tumblers are made of crystalline which is quartz molecules added to the molten glass and is not lead crystal although it has very similar properties. The crystalline gives a very good colour and sparkle and also makes the glass more robust in normal usage. These tumblers are perfect for all spirits with mixers and ice, oh and for water too! They will also compliment the best selling Villeroy and Boch Maxima range of wine glasses.
