The Ditanium Vaporizer Quartz Nail Insert will work as a direct replacement for your included quartz.  This bowl comes directly from the manufacturer so it will provide an exact fit.  Quartz Nails will naturally whiten over a period of time, so it's recommended to change your nail out occasionally to retain the best flavor and function. 

It is easy to replace the Quartz Nail Insert by turning your device off and unscrewing the assembly.  Then, simply remove the old Quartz and replace it with your new Insert and you're done!
