Bright yellow DUNLOP tennis balls for practice. - Brand: DUNLOP - Model: St.JAMES - Color: Yellow - Quantity: 85 - Usage: Tennis practice - Air pressure: 6/10 Thank you for viewing. All are used. They were used for about 3 months on hard and omni courts. The air pressure is about 6, with 10 being the pressure of a new ball. I think they can still be used for practice. Since they are used, no claims and no returns are accepted. tb001
