This kit is designed to be used with the Dragon Pen Kit (PKDRAxx). The pen you see here is not an inlay, it is a dyed-epoxy fill kit. All of the recesses in the Black-dyed Basswood blanks are filled with 2-part epoxy mixed with a bit of Bronze Pearl pigment which goes well with the Antique Copper Dragon twist pen. Also included in this kit is a packet of Gold and Dark Brown Pearl for the Antique Brass Dragon twist pen as well as a packet of Turquoise and Green Pearl for the Antique Pewter Dragon Twist pen. These perfectly match any of the 3 different Dragon pen platings with just 1 Epoxy kit.
