100 hard tennis balls used by a tennis circle. They can still be used for practice. Mainly Tecnifibre, but also includes Dunlop HD, Dunlop FORT, and Saint James. The balls are a mix of various new balls purchased online, which are opened and used gradually depending on the purpose. In addition, balls given by members from matches are also mixed in, so there are various types of balls. Tecnifibre in particular is similar to the previous Bridgestone balls and is a ball that is not easily deteriorated. ⭕️80 balls The photos are a part. C marks and (a few Y) are marked with red marker, so you can practice without mixing balls with other circles. We will continue to replace the balls regularly within the circle activities, so thank you for your understanding. We usually practice for about 2 hours once or twice a week, but the number of practice days has decreased this year due to the resurfacing work of the tennis court. These were used on an omni court. The balls are replaced little by little over time, so please understand that there are variations in condition, with some still in good condition and others with air leaks. They will be packed in a Tecnifibre cardboard box and shipped. They were inspected and packed today, so they can be shipped anytime. They are stored indoors and thoroughly dried except on practice days. Hard tennis balls The sales are always used for club fees. Please refrain from price reductions due to shipping and handling fees. Thank you for your understanding.
