Only around 3 months held

The case is described in the item description.
From Material wise, it is okay and does not stink.
The weak point as is often the zippers, they are gone after a few weeks break.
If the case fully stocked the zipper is very tight.
Since the substance of the teeth would be on each side must be approximately 3 mm longer.
Then not so much tension on the closure and he would not have broken.
