What is the bottle opener on the OpenFlow exactly?

The OpenFlow has a stainless steel bottle opener built into the base of the tumbler. It opens standard crown-cap glass bottles — beer bottles, soda bottles, etc. It is integrated into the base structure and will not damage or detach.

What is the capacity of the OpenFlow?

470ml — the ideal size for desk use, a couple of coffees, cocktails, or cold drinks out.

Is the OpenFlow a tumbler or a bottle?

It is an insulated tumbler — open top with no lid. It is designed for desk and table use, and not intended for bag carry with liquid inside.

How long does it keep drinks cold?

Up to 6–8 hours cold for an open tumbler — the double-wall insulation still significantly slows temperature change without a lid seal.

What material is it made from?

Food-grade 18/8 stainless steel. BPA-free. The built-in bottle opener is the same stainless steel as the body — it won't rust or corrode.

Can I use the OpenFlow for hot drinks?

Yes, but exercise caution as it has no lid. It is excellent for cold brew, iced coffee, cocktails, and cold drinks. For hot drinks, handle carefully as the exterior may become warm.

Is the HYV OpenFlow BIS certified?

Yes. The HYV OpenFlow is certified to BIS IS 17526:2021, India's national standard for stainless steel vacuum insulated bottles. Certification means insulation retention was physically tested by an accredited lab.

How long does it keep water cold or hot?

The double-wall vacuum insulation keeps water cold for around 24 hours and hot for around 12 hours. Real retention depends on ambient temperature, fill level, and how often the lid is opened.

What material is the HYV OpenFlow made of?

Food-grade 304 stainless steel (18/8) inner and outer walls with a vacuum sealed between them. The steel is corrosion-resistant, does not add a metallic taste, and does not leach chemicals like plastic can.

Can this tumbler be used for hot drinks?

Yes. The double-wall vacuum insulated construction handles both hot and cold. The exterior stays cool to touch even when the inside is hot coffee or tea.

What size is the HYV OpenFlow and who is it for?

The HYV OpenFlow is a 470ml bottle. Great for coffee, tea, short travel, and secondary hydration.

Rinse daily with warm water and a drop of dish soap. Deep-clean weekly with warm water + baking soda + a bottle brush. The lid disassembles fully so you can clean around the silicone seal — that's where cheap bottles trap mould.

Where can I buy the HYV OpenFlow?

The HYV OpenFlow is available on livehyv.com with free shipping over ₹499 and pan-India dispatch. It also appears in HYV's Shopify catalog and select retailers. Priced at ₹799 on livehyv.com.
