The Vollint Mini Green are Stage 1 tennis balls designed for children aged 10+ and adult beginners. They offer 75% of the pressure of a standard tennis ball to deliver slower speed and lower bounce and help players develop correct stroke technique. These yellow balls with a green dot can be used in Mini Green and Stage 1 tennis tournaments. They are suitable for use on a full-size court and feature a quality acrylic felt ensuring added durability and increased visibility on court surfaces. The Mini Green balls are perfect for training and match play and come in a handy mesh bag for convenient storage and transportation to the courts. They are supplied in a 5-dozen pack (60 balls).
