10m extension cable (Mosborough, S20)

10m Jo Jo extension cable reel with safety cut out. Dropped it recently and still works fully fine but have to pull out cable and wind more carefullyso that back casing stays in place. I have used like this several times but had to get onger one for outside use and just going to use that for both as don't need 2 anyway. Other option if can't be bothered wind up carefully is to keep cable loose and remove back of reel but I used it fine way is just need bit more patience to wind it up. Collection mosborough s20 prefer asap thanks.
