To inflate a ball pump is required with a needle the size of 4-6 lbs. If you do not pump at home, you can order such a ball pump with matching cap here at Amazon for a few euros the same time.
Once inflated convinced of volleyball. Its surface is medium soft and pleasant to the touch. When bunks fingers do not hurt. For older children the Volleyball is particularly interesting. Younger children, so my experience, prefer a slightly softer material.
The Volleyball line with our expectations. We opted for the Yellow / Blue / White model, which looks the same as the product images.
In short: The Volleyball Vetra can be perfectly playing in the hall. There are still no significant signs of wear. This coming summer we are on the beach examine the ball through its paces. Then I will again talk about the experience.
