A case of regular duty tennis balls for clubs, lessons and leagues. Regular duty suits softer courts, and the listing's size and included-item fields look like data errors.

Overview
Not a single can, this is a case of tennis cans with felt made of interlocked wool fiber over natural rubber. The description says the felt is applied evenly for consistent feel.
Reason to look at it: a bulk case of a familiar ball, which suits clubs and coaches who go through balls. The limitation is that the included components and diameter fields are clearly wrong.
Who it's for
Lesson programs, league nights and club courts are the situation here. Someone who plays on abrasive hard courts every week should look at extra duty balls instead.
Pros and cons
- Bulk case of 12 cans
- Natural rubber core per description
- Wool fiber felt
- Regular duty grade
- Included components field is wrong
- Diameter field looks wrong
- Not extra duty felt
Performance notes
Regular duty felt is thinner and wears faster on abrasive courts than extra duty felt, but it plays lively on clay and softer surfaces. The natural rubber core is credited with consistent bounce and reduced shock, and wear to the nap decides the lifespan.
