MILTON VACUUM FLASK DUKE 500 Blue

Milton Duke 500 Blue Thermosteel Vacuum Water Bottle

The Milton Duke 500 Blue thermosteel water bottle is a straightforward, everyday flask built for people who want reliable insulation without fuss. It's worth knowing upfront that while the model is named Duke 500, its true fill capacity is approximately 400 ml, so buyers should judge portion size by that figure rather than the name alone. Made from stainless steel with double-wall construction, it keeps beverages notably warmer or cooler for longer than an uninsulated bottle, and the blue finish gives it a clean, everyday look.

The Duke is built as a simple, no-frills bottle — sturdy steel construction, a secure lid, and no plastic touching the drink inside. It's a dependable choice for a desk, a school bag or a short commute, and its straightforward design makes it easy to trust when buying online.

For a genuine, brand-authorised Milton purchase in Varanasi, Girdhar Das & Sons has been a trusted name since 1970. Shop online at gdsons.co.in or visit the store at W.H. Smith School Road, Sigra, Varanasi.
