The crystal is easy to work with. I measure every piece before I engrave and their dimensions are within 10% of each other.

This is an excellent product to work with due to the Bright LED Light and the quality of the Crystal.

These come individual gift box packaged. Very nice add on to our engraving company.

As soon as they see one of these, everyone who has crystal inter engraving capabilities has to know where to get them. The xTool K5 Crystal Keychains are easy to inner-engrave with the F2 Ultra UV with names and characters. I like to include them as gifts for collaborators. I engrave their company logo inside and include them with their order. You should see their eyes light up when the multicolored lights show off their business! Even when the replaceable battery runs out the amazing engraving still shines and that brings me to the question: Can xTool find a source for reliable affordable battery replacements? Right now it seems replacing the batteries with a long lasting option costs as much as the keychain itself. The Keychains come nicely packed in a sleek black box which also can be engraved.

The rectangle k9 crystal keychains bring a real unique gift for our business. To provide a custom gift with a picture of a loved one to see all the time.
