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.
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players.
