Brought this set of four back from Belgium 50 years ago, having so enjoyed the coffee made in them at the various cafes. Made in France. Keep your coffee or drink hot or cold, using the lid (or not). They're indestructible with heat tempered glass and stainless steel comprising the rest. In perfect clean condition as new. Dishwasher safe. Can be used for teas, of course - ideal when guests or family want different options. Easy to use and attractive - the 'now' industrial look. Very 'European' looking.
