Frequently Asked Questions
Does the bottle opener actually work well?
Yes. The opener is a full-size stainless steel opener integrated into the base — not a token feature. It works on standard crown-cap glass bottles.
Is this a good coffee mug?
Yes. At 470ml it's the right size for a large coffee or two espresso shots with milk. The insulation keeps coffee hot for several hours.
Does it come with a lid?
Yes, the OpenFlow ships with a lid. Check the product images for lid details.
What is the replacement policy?
We offer free replacement within 7 days of delivery for manufacturing defects or damage on arrival. Contact us at support@livehyv.com with your order details and photos of the issue.
"The only bottle that opens two kinds of cold."
A 470ml insulated tumbler with a stainless steel bottle opener built into the base. Designed for the space between the gym and after — when the water bottle goes in the bag and something else gets opened. The opener is always with you.
The compact that fits everywhere.
470ml — the size that fits every cup holder, slips into a jacket pocket, and does not add weight to a gym bag. The compact form factor is a deliberate choice, not a limitation.
