The stem of the Stainlees (steel) model with a diameter of 12 mm is fully collapsible and based on steel alloy AISI 304. The model is rather weighty.
The main element that has been criticized by the first models of Dusha hookahs was the diffuser, which made the pull much heavier due to the lack of an optimal number of holes. Its design has been fixed in the new versions, and the diffuser of the old model can be purchased separately.
