I've only ever had to fix two items in the course of me making these... usually they hold up very well... and if anything I've had more shattered stones than anything else (people hitting the conchos up against something metal or purely misuse) Id still be more than glad to fix them.. but in that case buyer pays for materials and a tiny tiny donation to my time... I've never had a repair go over $5 with shipping back.
This is not a all the time pricing. It will last at least till christmas.. and possibly a few days after. Just depends on sales :)
