I had to buy more closure, as in the bottle my daughter a little white rubber insert is lost and therefore the closure was no longer tight. This small rubber stopper you can not buy more separately unfortunately, so I unfortunately had to buy the entire essay, which is a bit annoying. The price is not exactly without (especially the cover is indeed not even in that one would have to again buy extra, if you have such. B. lost the whole essay), when I consider that I have the bottle on offer for just 15 Euro have bought. Nevertheless, I have to say that this article (or the whole Alfi bottle) so far the best I've bought. He is really tight and the children come along great with the rotary mechanism for opening. The point deduction is only available for the high price of the spare part and because you can not buy more the rubber plug separately.
