Dafla or Nyishi, people inhabit a vast expanse in the eastern Himalayan zone of Arunachal Pradesh in Northeast India. The way of life of these tribes has been really environmental friendly attitude in the use of bamboo, which is very important in household and ceremonial artifacts. The importance of the bamboo vessel is because it is one of the important bamboo utensils and reminds one of the skills and handiwork formed through clever use of Nature.

The bamboo vessel forms a hollow module with thickened ends at both ends, the one being perforated at a distance about. Thus, the node contributes to a closed container module, which needs no artificial lids or covers. Usually, one end has a small hole pierced through the node, and the area around this hole usually resembles a bent tube, allowing controlled pouring of contents or direct consumption of contents from the vessel's end. This is an indication of the deep knowledge of structural capacities and of using bamboo. Traditionally these vessels are used by the Dafla for storing water and the transportation of rice beer (""opo"") and other fluids. They are lightweight, strong, and ecologically friendly, making it easy to transport them through hilly terrain of Arunachal Pradesh. These vessels bring forth for the highest purposes the eco consciousness and creativity of the Dafla tribe. Such indigenous practices have just started to gain ground in the modern world because of their highly sustainable and biodegradable nature fueling the constantly evolving trend of eco-aware living conditions.
