I keep usually only 2 mouthpieces with me, but sometimes I need more so I got this pouch.
It offers great protection for the mouthpieces, and my pieces always look in better shape than my section mates'. ;-)
It worked fine until after 6 months, one of the belt straps came loose on one side. The stitching was a little too sparse, so the leather broke off.
Since it's real leather, it was no problem to fix it myself with a needle and some thread.
