This is a great way to find additional information about the ball. When I’m buying online I always look if I can find something like this. Just take a look at that and you will for sure find extra information. When you are buying local this is a little bit harder, but you can still ask the vendor or somebody that has already bought that or similar ball in that shop.
When it is about quality, these are almost same as premium match soccer balls but obviously not the same. To be exact, you can say official match soccer balls are positioning between premium match balls and training soccer balls regarding quality. That means these balls also offer an excellent level of air retention, shape, water absorption, curve, and performance. Although usually, they are not as durable as training balls but as a whole, they are very much durable.
