The Bontok construct baskets of bamboo, abaca, and rattan. No surface decoration is used beyond the natural pattern of the weave.
Bontok storage baskets are generally narrow towards the mouth and bulge at the waist.The shape given to rice baskets supposedly mimics that of ancient Chinese porcelain jars, which are considered precious. Like the Ifugao kalbong and ulbong, these are single-rod coiled baskets.
The black color of Bontok storage baskets, like that of the Ifugao's, results from the special heat-conserving construction of the houses. There are no windows, and the smoke from the hearth tends to permeate the small structure, resulting in a sooty black finish on many objects that remain indoors.
Lunch boxes are an important item, and come in many sizes and shapes.
