Penn Payne was once the world's largest tennis production company, with a 30% global market share, and even 50% in the United States. The bright yellow look of the tennis ball we see today is a design from Penn, a change that not only makes it easier for players to keep an eye on the ball, but also makes it easier for the tennis ball to be captured by the camera.
 
The world's first canned tennis ball was also invented by Penn. Generally, the pressure-free tennis ball is blunt and the flight speed is slow, so it is only suitable for practice. The pressure ball has better resilience, fast ball speed, strong ball feeling, obvious hitting feeling, and hitting comfort, so it is mostly used in competitions. Penn places the tennis balls in a sealed pressurized tank to provide a balanced environment that greatly maintains the performance of the tennis balls, which is basically the packaging method used today.
 
The current Penn is relatively quiet and does not highlight innovation. Tennis has two types of tennis for competitions: PRO Penn and CAN ATP, and Penn COACH can be used for daily training, while other tennis balls suitable for daily and amateur competitions such as CHAMPIONSHIP and Control are rarely sold separately on Taobao, and can only be purchased in whole boxes or purchased through overseas shopping, which is less cost-effective, so it is not recommended.
 
The PRO Penn uses Encore technology for excellent resilience and good rebound on any type of course. Another advantage is that its ball felt has high brightness, but unlike Dunlop's high-brightness balls, PRO Penn is more fluorescent, so it is suitable for use in low-light outdoor conditions, and the price of 3 capsules for 25 yuan a can is worth buying. Another CAN ATP tennis ball, biased towards hard courts, has a more consistent rubber structure and less impact on the wrist, and is available on Amazon, but because of the small quantity, the price is relatively high, and a can of 3 capsules costs about 50 yuan. But compared to the brands before the recommendation list, Penn's competitive tennis is more tour-level and less performance-intensive.
 
The felt used in the practice ball Penn COACH has only about 50% wool content, so the cost is lower than other brands. However, this does not affect its use, when the racket hits the tennis ball, you can still hear the whoosh sound of impact, and the additional rebound can also increase the spin and accuracy of the tennis ball, and the price of a can is around 20 yuan.
