The Wartmann® transparent vacuum cup has been developed for storing your juices and drinks under vacuum, but can also be used as a regular drinking cup. By placing the Wartmann® vacuum pump on top of the special vacuum cover, the vacuum cup is simply vacuumed. Included is a drinking lid with a drinking spout with protective cap. 
 
 A slide protects the cup against accidental opening of the cup during transport, for example. 
 The recommended maximum content is 400 milliliters. The Wartmann® transparent vacuum cup is made of Tritan and does not contain biphenol-A.
