X-OUTS
X-Outs are name brand golf balls on which the name brand has been crossed out. During the production process if an error is ever made and blemishes are found on balls, instead of simply throwing the balls out the name brand is crossed out (usually with X's) and sold at a discount.
Many golfers confuse X-Out balls with refurbished balls. Refurbished balls are normally golf balls that have been found on a course, cleaned up, and then sold at a discounted price. Refurbished balls are not golf balls that were damaged during the production process.
