Abstract: A golf ball holder is adapted to hold a golf ball while drawing a circle on the golf ball using a pen, and includes a supporting plate adapted to support the golf ball thereon, and an annular surrounding unit disposed on the supporting plate. The surrounding unit is adapted to be disposed around the golf ball such that a lower half portion of the golf ball is disposed within the surrounding unit and an upper half portion of the golf ball is disposed outwardly of the surrounding unit. The inner diameter of the surrounding unit is approximately equal to the diameter of the golf ball. The surrounding unit is structured so as to allow a pen to slide on the surrounding wall, thereby drawing the circle on the golf ball.

Abstract: A golf ball pick-up device includes an upright pick-up tube having an upper end portion formed with a ball-exiting opening. A strip unit includes plurality of resilient strips extending radially and inwardly from an open lower end of the pick-up tube so as to define a ball inlet thereamong. The strips deform so as to allow golf balls to move into the pick-up tube via the ball inlet when the strip unit is pressed against the golf balls one at a time, and is sized so as to prevent downward removal of the golf balls from the pick-up tube via the ball inlet. A ball-guiding unit is disposed within the upper end portion of the pick-up tube, and is formed with a ball-guiding surface shaped so as to guide the golf balls into the ball-exiting opening when the golf balls move upwardly within the pick-up tube.
