As described, these are used to "practice" balls have now also bought a few times and only now I read the bad reviews! I find that quite unfair to the product! Honestly, I've always been very satisfied with the quality! They're much better than I thought! I do not know what that has a user! The balls are top for practice! If you are looking tournier balls you buy new! It is a price-performance ratio! The bag admittedly not quite as top but it handy! And if the pvc bag does not fit simply the balls take out the bag throw in recycling bin!
