As silly as this tip may seem, you would be surprised by the amount of players who injure themselves right before a match opening a fresh set of balls.
For optimum safety, use the lid of the can to flick the tab up. This makes it easy to remove the foil lid. Also, if you pinch the top ball in the can, the added pressure helps release the seal while making sure you don’t lose your balls.
Avoid unnecessary injury and open your next can of balls like a pro!
