Until then, nothing very sorcerer.
These pouches fulfill their primary function, but two are to report.
First, as others have commented previously, the bags are quite fragile. For a very simple use, they suit perfectly. For more intensive use, they risk quickly to the face (and you too).
Second element, the size of these bags. Indeed, we are told in size 6x9cm. But the part under the zip actually measures 8x6cm. So beware if you have an element with a defined waist!
