Cello Vacuum Flask Duro Kent 900 860Ml Black

Cello Duro Kent Vacuum Flask – Black, 900 ml (ISI Certified, 24-Hour Hot & Cold)

The Cello Duro Kent Vacuum Flask in Black – 900 ml is a large-capacity, ISI-certified stainless steel flask from Cello's Duro series — designed for users who need their beverages to stay at temperature through a full workday, long commute, or extended outdoor activity. With an actual capacity of approximately 860 ml, it holds enough hot tea, coffee, or cold water for 3 to 4 generous servings without refilling. The bold matte black finish gives it a confident, professional appearance that suits offices, gym bags, and travel backpacks equally well. Made from Grade 304 stainless steel with double-wall vacuum insulation, the Duro Kent is rust-proof, BPA-free, and keeps beverages hot or cold for up to 24 hours.

The Duro Kent's ISI certification from BIS confirms it meets Indian national safety and quality standards for vacuum flasks — an important marker for a flask in this size category where build quality consistency matters most. The screw-top lid creates a reliable, spill-proof seal suitable for carrying in bags and backpacks during active commutes. The stainless steel interior is odour-free and non-reactive, ensuring every beverage tastes as fresh as when poured. As with all Cello Thermoseal flasks, Cello recommends pre-conditioning with hot water before filling hot beverages. The Duro Kent is available across Cello's retailer network and is backed by a standard Cello product warranty.
