Mikasa V300W Volleyball, yellow and blue design, official match air pressure range. - Brand: Mikasa - Model: V300W - Air Pressure Range: 294-331 hPa, 0.300-0.325 kgf/cm², 26.4-48.2 psi - Color: Yellow/Blue Thank you for viewing. I failed to replace the valve, and it tore off mid-way, falling inside the ball, so there's a rattling sound. I replaced the valve afterwards, but the air leaks out after a day. It might be usable for self-practice for an hour or two. If you're okay with that, please consider. The team name is erased with a marker. If you're okay with shipping it deflated, I can offer a slight discount.
