High-quality bag for 9 bottles but

in the product description does not say that it is only certain types of bottles.
Empty milk bottles made of glass or juice bottles made of glass, you can not pack into the crowd 9, because they are too thick for the hole. Since I had bought it for empty milk bottles, it has not paid off.

If someone wants to use for PET bottles, it is a good möglichkerweise and quality product, but I can not judge.
