The Na Grani Heat Management Device aka 'Over The Edge' is made completely from 1 piece of AISI 304 stainless steel.
This means it can get a lot hotter than aluminium HMDs such as the Kaloud Lotus.
You can use this with 2 coals and it would be hot enough for a blonde leaf session, or you can go crazy and add 4 coals for a real Russian dark leaf session.
The Na Grani HMD has a raised section within the coal area to aid airflow as well as several holes so heat reaches your shisha tobacco evenly and stop coals.
