My policy is simple when it comes to a guarantee or warranty on my products.
MAKE IT RIGHT. This means if your holster for whatever item does not fit like you want, I will continue on the project until it is how you want it... unless you are trying to violate the laws of physics.
When you buy a product from me, it has a lifetime guarantee in materials and workmanship. This guarantee covers the original owner, the next owner, the 27th owner. It does not matter. If I made it, I made it to last and it is covered.
Use it. Abuse it. If it wears out--not likely-- send it back and I'll refurbish, repair, or replace it at no cost to you except for the shipping.
If there is anything you are unhappy with, if it's a product, service, anything... contact me, and I WILL make it right.
How can I do this? It's simple. I make it to last, and if I'm not happy with it, it doesn't leave the shop.
Now, I do have to put one caveat here, and that is if I request you to ship the item you want a holster for, and you decide that no, you don't want to ship it, yet have me make a holster/pouch/sheath for it anyway, I will attempt it ONCE. If you are not willing to ship your item (and I don't request this very often) after the first time. We are done. Would you have a suit tailor made and refuse to go into the shop to get fitted? I didn't think so. I'm damn good... well, better than good, but I'm not THAT good. If you meet someone who is, you have died and met the Lord. Accept it.
