The Pexpo Oslo Vacuum Flask – 750 ml in Pink is the Oslo Art variant — designed for those who want the same trusted Tri-Ply insulation of the standard Oslo but with an expressive, printed art design that makes the bottle more personal, built on the same Tri-Ply vacuum technology and ISI-certified stainless steel construction that defines the full Oslo range. The bottle features a vibrant pink base with a flamingo bird art print, a silicone carry strap for hands-free portability, and a secure airtight screw lid that prevents spills during daily commutes, travel, or gym sessions. Constructed from food-grade SS 304 stainless steel using Pexpo's proprietary TPVT (Tri-Ply Vacuum Technology) — three layers of BIS-grade metals: SS304, aluminium, and SS304 — it keeps hot and cold beverages at temperature for extended hours. ISI certified, Made in India, and backed by a 1-year warranty.
The Oslo's defining physical advantage over standard two-wall flasks is Pexpo's TPVT construction: a thicker aluminium core sandwiched between two stainless steel layers, with vacuum insulation between the outer and inner walls. Pexpo's internal testing confirms this configuration provides better temperature stability and durability than a standard copper-coated double-wall alternative. The silicone strap makes the Oslo uniquely travel-friendly — it loops over a wrist, clips to a bag, or hangs from a gym rack without a separate carry pouch. Amazon.in reviewers consistently highlight the Oslo's leak-proof reliability and premium build quality, with one noting it kept water cool for over 7 hours in direct summer sun. However, a cluster of reviews across the Oslo range flagged the plastic cap breaking within a few months of regular use; Pexpo's after-sales service has responded well in replacement cases, but carrying the bottle by the lid rather than the strap is recommended to reduce cap stress.
Three layers of BIS-grade metals with a thicker aluminium core provide better temperature control and durability than standard double-wall copper-coated alternatives. Independently tested to BIS IS 17526:2021 and European EN 12546 standards.
At 750 ml, the Oslo holds enough for a full office morning, a gym session, or a school day of hydration without refilling. The screw lid is airtight and leak-proof — safe for carrying in bags and backpacks.
The integrated silicone strap makes the Oslo one of the easiest flasks to carry hands-free. It loops over a wrist, clips to a bag hook, or hangs from gym equipment — removing the need for a separate carry pouch or jacket.
High-grade SS 304 construction resists rust, bacteria, and odour, ensuring beverages taste clean and pure. ISI certification confirms the flask meets Indian national safety and quality benchmarks. 1-year manufacturer warranty.
All components are BPA-free and food-safe. The Oslo is a reusable, sustainable alternative to single-use plastic bottles — built to last through years of daily hydration. Avoid carbonated beverages and hand-wash only.
