this is a barely used 20 watt diode laser that comes with an enclosure and a brand new still in the box fire control system and a RA-2 roller for tumblers and glassware engraving never used I did some ceramic tile permanent engraving and some colored images also and I have many tiles done mostly in a 5.5 watt engraver I don't use it because I have an 80 watt fiber laser I also have extended legs to raise the height for larger objects or to run the roller if interested call Ron at 727-645-nine 7 one 9
