Floor-to-ceiling punchball / boxing ball (Marchmont EH9)

Not quite sure what this is called exactly but it’s held between two lengths of thick elastic rope (with clips on the end) for boxing / martial arts practice. One end of one side of the rope/ elastic has lost its clip but with some dexterous problem solving it can still be set up to work. Pick-up preferred from Marchmont; tho can deliver if it’s on a route I take. Cheers! Dave
