1. You can use the same tab on the same client so you aren’t using them up quickly. You just flip it over and use the other side if to much wax builds up.
2. If you wait to long to put the tab on or you wait to long to pull the tab the tab may come off without the wax. If this happens just put a little wax at the end of the wax where you want to put the tab and replace the tab and them pull.
