These balls are made of the exclusive flexton silpower® (patent) material developed by our company and if used in accordance with the requirements contained in the instructions and warnings manual, they slowly deflate in the event of accidental damage caused by small tears or punctures, thus providing a safety factor to the user. Available in white pearl colour and in 3 different sizes, as the Original Pezzi® Hi–Fit STANDARD, these balls offer a pleasant soft and velvety surface. The white colour of the Original Pezzi® Hi-Fit Maxafe® balls makes them particularly suitable for fitness and aerobics programs. Furthermore, cuts (up to 5 mm.) or small holes , can be repaired with the specially designed "Fixa-Kit". Each ball supplied in box is provided with a complete exercises guidebook in 6 languages.
