Z-plus problem in Zippo case

[T.G]

Everything about a Zippo lighter has a lifetime warranty EXCEPT the hinge because there are so many trick ways of opening a Zippo, some of which kill the hinge over time. So, if it's a hinge issue on your zippo, you're probably out of luck.

As previously mentioned, Zippo doesn't make the Z-Plus, so you'd have to take that one up with whomever makes it.
