4" diameter imprint area for your logo. Made of high quality ionomer material. Must-haves for golf outings, charity events, company picnics, and end-of-the-year gifts. Even if some clients don't like playing golf they'll still enjoy receiving a personalized white golf ball as a keepsake. Golf balls make great mementos. For those that love the game, offer them some of your custom golf balls at the beginning of the event and let them take the balls home after.
