Used tennis balls are used to reduce unpleasant noise made when moving desks and chairs in classrooms by attaching the balls to feet of desks and chairs.
Since 2003, members of the entire NEC Group companies assist in these activities by collecting used tennis balls as part of NEC Make-a-Difference Drive.
Today, this activity is supported by donations from tennis schools and those outside NEC Group who support our activity.

As of the end of March 2018, approximately 231,000 used tennis balls were donated to 182 elementary and junior high schools.

Using used tennis balls which would have been discarded for the most part reduces the environmental burden.
