The high-quality water bottle (550 ml) with integrated magnet in the bottom has been made from clear borosilicate glass and can be protected during transport with a removable neoprene sleeve. The base that can be unscrewed to remove the stainless-steel sieve is a special highlight. That’s because it’s possible to fill the sieve individually but it’s also great for the BalancePlus Mix – one of which is already included with the bottle.
