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.

Best Vacuum Flask Ever!

I recently bought the MILTON VACUUM FLASK DUKE 500 Blue, and I couldn’t be happier! The delivery was super quick, arriving right on time. The packaging was solid and ensured the flask was safe. I've been using it daily for my tea and it keeps it hot for hours! It’s really lightweight, so I can carry it around with me easily. The blue color is vibrant and looks great. I love it so much that I’m thinking of buying another one for my sister. If you're looking for an affordable and high-quality flask, this is it! Highly recommend it!

अच्छा फ़्लास्क है

MILTON VACUUM FLASK DUKE 500 Blue का उपयोग मैंने कुछ हफ्तों से किया है और मुझे ये बहुत पसंद आया। पानी ठंडा रहता है और चाय गर्मी में भी। इसका वजन हल्का है, और ले जाने में बहुत आसानी होती है। डिलीवरी भी समय पर हुई थी और पैकेजिंग ठीक थी। अगर आप एक अच्छा फ़्लास्क ढूंढ रहे हैं, तो ये सही रहेगा।

Good Flask for the Price

This MILTON flask is quite good for the price. It keeps my drinks at the right temperature, and I appreciate that. The delivery was prompt, and it came in nice packaging. However, I noticed that it could be a bit more sturdy. Other than that, I’m satisfied with my purchase. It’s been a good addition to my daily routine.

Great for Daily Use

I've been using the MILTON VACUUM FLASK DUKE 500 Blue for a few weeks now, and it has really helped me stay hydrated throughout the day. It keeps my water cool and refreshing. I ordered it online, and it arrived quickly without any issues in packaging. It’s a good size, fits perfectly in my bag. My only complaint is that the mouth could be a bit wider for easier cleaning. But overall, I’m pretty happy with it!
