I have held one of these brushes, they are used in Burger Kings, they are the hardest bristles I have ever felt, they are like steel!!! they use them to clean the tiled floors, don't get one you will be dissapointed. I saw them at acarboot sale, a Burger King franchise had gone wrong
Hi
The suggestion Luke was to buy the brush, remove the swivel and throw the brush head away.
Gaz's mk1 swivel also had an additional insert to prevent the horizontal from pivoting to far.
