800 ml replacement drinking bottle for a magnetic-mechanical bottle holder system. Every bottle wears out over time – even the Twist Bottles can't work miracles. When a Twist Bottle is worn out, the bottle body can be detached from the sustainable magnetic connector and replaced. The change is simple: unscrew the belt from the connector, remove the connector from the bottle, place it into the new bottle, wrap the belt around the new bottle, insert the screws, and tighten them – cheers!.
