Question about store policies

I received the following email about store policies:
"I have a question regarding your store policies. I have some customers that ask me "how secure is wire wrapping?" They are worried that without glue or a screw setting that the jewelry will break more easily. What would your response be to a question like that? Also, I was reading in your journal and saw that the core wire in one of your bangles broke. How did you handle that situation with your customer? Do you have a guaranteed for ?? days policy?"

My answer was the following:
I normally tell them that while I test all my jewelry, hand-crafted jewelry is a bit more fragile than commercial jewelry, so they should care for it a bit more.
The few occasions I've had pieces break, I fixed it for no extra charge, except shipping. No day limitation.
