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 in the new bottle, wrap the belt around the new bottle, insert the screws, and tighten – cheers!.
