The Blenderbottle Classic is a long lasting and sturdy shaker. Thanks to the robust materials the cover and lid close very well, so the shaker is absolutely leakproof and could be put in a sports bag for instance.
Each Blenderbottle Classic comes with a Blenderball made of surgical steel. Put this ball in the shaker before you shake and you'll get a very well mixed shake guaranteed, without any lumps. Both shaker and ball are dishwasher safe.
The Blenderbottle Classic does not contain any toxic plasticizers (BPA-free). The shaker has a capacity of 400 ml and has a measure indication.
