The Lookah Dragon Egg is a load- your- own concentrate vaporizer that acts as a portable e- rig! The Dragon Egg is compatible with the same coils used for the Swordfish: 710- threaded, porous quartz buckets! The chamber and percolator are made with durable food- grade plastic, and the device has a clamshell bracket over the coil that flips up for easy loading. The three voltage modes and battery level can be seen on the built- in LED screen.
