“Heavy duty glass jar fits nicely in your hand. The small top makes it easy to drink from the jar. The big lid and size of the jar opening makes it easy to clean as you can easily fit your whole hand and scrubber inside. The gasket inside the lid is easy to remove and replace during cleaning. The big lids are interchangeable with other of their 900ml and 1400ml jars. Stylish and practical.”
