The tiles that we make in the class are the most basic patterns which have a success rate of about 99%.   Tiles do occasionally have a crack or other imperfection.  In this case we will remake the pattern and try to recreate your signature and send both your original tile and our successful remade piece.  Although every effort is made to ship tiles in a manner that avoids breakage in transit we do occasionally experience this situation.  We keep original pattern and color information for a period of time and will use this to recreate the tile front and back if you can send us a photo of your signature. In the event of breakage we will also send along some extra goodies from our retail shop as well. Our goal is 100% satisfaction.
