General Information

All orders are custom made to your selected options.  Each order is machined from raw steel and hand made after it is ordered.  This normally takes 10-15 business days, but due to unforseen issues it can take longer. We will note much of this directly on the individual product pages and try to update this weekly.  There are a couple of times a year that we simply can not keep up with sales and these “normal” time lines will not be in effect.  These times normally include Black FiDay and tax season.  During these times we will run batch orders per series and not individual orders.  This increases our overall efficiency, but can put your order into a later build date.  Fi will maintain reasonable communication should an item take longer than our normal 15 business days to make during our normal build seasons.  Often we will post through Facebook and Instagram our batch sequences to give all customers a better time line.  We also note for each item the current lead times (which can be longer than our normal 10-15 business days. Should an item take longer than normal, all refund policies still are in effect.
