    The Borosil Bolt Vacuum Flask 500ml is a compact, everyday water bottle built from 100% food-grade, rust-proof 18/8 stainless steel (Grade 304) inside and out. Its double-wall vacuum insulation with copper coating keeps drinks hot for several hours and cold for even longer, making it a handy companion for the office, gym, school or daily commute. The screw-type lid is leak-proof and drip-free, and the bottle's condensation-free exterior keeps your hands and bag dry even when carrying ice-cold water. A wide mouth opening makes it easy to add ice cubes or clean the bottle thoroughly, and its compact 500ml size fits comfortably in most bags and cup holders. Backed by a 1-year warranty against manufacturing defects, the Bolt 500 is a durable, practical choice for everyday hot-and-cold hydration. The Borosil Bolt Vacuum Flask 500 is available at Girdhar Das & Sons, Varanasi.

    Perfect for Everyday Use

    I recently bought the Borosil Vacuum Flask Bolt 500, and I couldn't be happier! The stainless steel design is not just sleek, but it also keeps my drinks hot for hours, which is perfect for my busy mornings. The delivery was super quick, arriving just two days after I ordered. It was nicely packed, which shows how much care they take. I've used it for both coffee and tea, and it performs beautifully. Plus, the size is great for carrying in my bag without taking up too much space. Highly recommend it to anyone looking for a reliable flask!

    Excellent Insulation

    बोरोसिल वैक्यूम फ्लास्क बॉल्ट 500 ने मेरी उम्मीदों से बढ़कर काम किया। यह गर्म पानी को कई घंटों तक गर्म रखता है। डिलीवरी भी तेज थी और पैकेजिंग बहुत अच्छी थी। मैं इसे रोजाना अपने साथ ले जाती हूँ। बस एक बार में काफी पानी आ जाता है, जो मुझे बहुत पसंद है। ये एक बेहतरीन प्रोडक्ट है, मैं जरूर सभी को इसे खरीदने की सलाह दूंगी।

    Good Value for Money

    I bought the Borosil Vacuum Flask after reading some good reviews, and overall, I'm satisfied. The flask does keep my drinks hot, but not as long as I expected—maybe around 4-5 hours for hot beverages. Delivery was quick, and I appreciated the sturdy packaging. It's a bit heavier than some other flasks I've used, but the quality feels solid. For the price, it’s a good buy, especially for daily use. Just wish it had a slightly better insulation time!
