What ₹500 Buys vs ₹899
₹500
Single-wall: no insulation, no BIS

Cold retention (single-wall in summer)
The Honest Answer on Sub-₹500 Bottles
Every vacuum-insulated bottle involves a specific manufacturing process — double steel walls, industrial vacuum pumping, sealed ends, and leak-tested lid assembly. This process has a cost floor that makes BIS-certified vacuum insulation economically impossible at sub-₹500 prices in the Indian market in 2026. Any bottle claiming vacuum insulation at ₹300–500 either has no measurable insulation, uses a compromised vacuum process, or makes false claims.
