## Questions & Answers

**Q: how long lifespan of 1 ball ?is it destroying over time?**
A: Yes, a Kenko soft tennis ball does have a limited lifespan. The ball must be properly inflated so that when it is freely dropped from 150 cm high the first bounce should be 75 cm +/- 5 cm.  How long is the lifespan?  I don't have any good answer but I can share our experience with you. We have a group of seniors who play doubles using two balls for about two hours in a session.  The balls usually last for 6-8 sessions. The rubber balls are subject to wear and tear. The harder you hit in rallying, serving, or overhead the shorter the lifespan will be.
FYI:  In 2013 we uploaded four short videos on YouTube named "Alhambra Park (near Pasadena, CA) Soft Tennis."

**Q: What is the weight of each ball?**
A: The weight is 1 oz.

Thanks

**Q: What i s the  diameter of t he ball?**
A: The diameter of a soft tennis ball is between 6.5cm and 6.7cm. For more information on playing soft tennis, please visit the website of the International Soft Tennis Federation.

**Q: Where can I buy soft-tennis rackets in US?**
A: Dear buyer. We have the set of raquets that comes with a couple of balls pluss the inflator

## Customer Reviews

### ⭐⭐⭐⭐⭐ Finally! The RIGHT tennis ball!!
*by S***T on April 2, 2025*

Perfect for real soft tennis - not tennis balls that happen to be softer, not the balls that are made of foam, but actual soft tennis, rubber balls. It really shouts be difficult to find in the US, but it is, and if you can actually find them, the shipping is more than the product. I shared it with my niece who plays high school softball tennis, and I use to em for a squeezy stress ball when I’m in physical therapy.

### ⭐⭐⭐⭐⭐ Gentle Tennis Balls
*by N***S on July 30, 2025*

I use these balls to play tennis. They are very gentle on your arms and wrists. If you ever start to get pain from playing tennis using the standard tennis balls, you will find comfort in using these.

### ⭐⭐⭐⭐ Good and available in the USA
*by P***E on August 7, 2016*

Though Kenkor soft tennis balls are approved for use by the International Soft Tennis Federation, personally, I like to use another approved balls brand named Akaemu (or red M). Akaemu balls bounds better, plays better and are easier on elbows. Unfortunately, Akaemu balls are not yet available in the USA.
