This magic pen allows you to mark any pool/snooker cloth.
This is used for when you have just started playing 6reds and the table does not have the proper spots marked by a table fitter.
Also used by coaches or in training sessions to mark positions on where to place balls.

You can easily remove the marking with a damp cloth.

To apply, just mark the table where needed once. The color will come through after about 30 seconds.
