I take pride in making great looking, functional grips. From time to time, I do make a mistake or a material defect makes it to a finished set of grips. If at the time of receiving your grips you are not satisfied in the product that I shipped, please use the contact page on this site to notify me of the issue. I will repair, replace, or refund at your discretion. Refunds are made after the grips have been returned to me.
