First, I am very pleasantly surprised by the quick delivery. What I find less well, the fact that all balls were loose in carton box, which I found less good because it has indeed acted to 200 balls (normally 2 packages). I would have expected that they would be packed. So I counted them all, to assure myself that at least is true the number. The result was very good, because there were at least 200 balls, probably two more. Since I have given away the balls, I can not say much about its quality, but standing in the description that they are low in pollutants. This was also one of the main reasons to buy them for me. Those who do not necessarily need a packaging, is well advised here.
