Cut slits into the face of the ball along the cross lines.

Be careful not to make the slits too long.

(If they are, the ball will come off the feet easily.)

4: One ball done

That completes the cutting of one ball.

Do the same for the remaining balls.

5: Remove any liquid inside

Liquid remains in the balls.

Remove it.

Liquid remaining in the balls erodes the feet of desks and chairs.

To avoid this, put the balls in a place with good ventilation such as near a window until the odor is completely removed.

6: Attach to the feet
