What materials do we use?

We use certified high-grade 304 (18/8) stainless steel. It’s double-walled, vacuum-insulated, and completely free of BPA and toxins.
That means no weird aftertaste. Just safe, clean sips. Again and again. Built to last, and better for the planet.

Is my FLASKE leakproof?

Absolutely. Our bottles and cups are 100% leakproof.

You can toss them in your bag with confidence. No spills, no surprises. Just one less thing to worry about in your day.

What is an EVO product?

EVO stands for Evolution.

This is the next generation of sustainable drinkware. It’s smoother in your hand, lighter in your bag, and designed to match your lifestyle.

With matching leakproof lids, refined shapes, and stunning colors, every detail is elevated.

And yes, you can personalize it so it’s not just a bottle, it’s your bottle. For yourself, or as a gift that actually means something.

What is the difference between EVO Series and Original Series?

The Original is where it all began: timeless, sturdy, and built to last.

The EVO takes it a step further: softer curves, a more elegant feel, and an upgraded finish that makes every sip feel a little more special. Including a colored match lid and a carabiner.

Both share the same high-quality, double-wall insulation and 100% leakproof design.

Is it safe to use a stainless steel water bottle or coffee cup?

Yes, absolutely. Our bottles and cups are made from 18/8 food-grade stainless steel, one of the safest materials you can drink from.

It’s non-toxic, BPA-free, and doesn’t need a plastic liner. Even when dented or filled with hot drinks, it won’t leach chemicals unlike plastic.

Plus, it’s ultra-strong and way safer to travel with than glass. Just refill, sip, and go, with peace of mind.

Can I use FLASKE for sparkling water?

Yes, your FLASKE can handle sparkling water.

Just don’t fill it to the very top.

Carbonated drinks build pressure, so it’s important to leave a bit of space. When opening, always do so slowly to release the pressure gently.

That way, you avoid spills and enjoy your bubbles safely, wherever you go.

Kan ik mijn FLASKE meenemen als ik vlieg?

Ja, zeker weten. Zolang je FLASKE leeg is bij de security, mag je ’m gewoon meenemen in het vliegtuig.

Nog beter? Op veel luchthavens kun je je FLASKE na de controle bijvullen met vers drinkwater.

Reis lichter, vlieg slimmer en sla de wegwerpflesjes over.

Flessen

Can I put my FLASKE in the dishwasher?

Yes, you can. Up to 60–65°C. But for the longest-lasting joy, we recommend washing it by hand.

Use warm water, our cleaning tablets, and the FLASKE brush to keep your bottle fresh, shiny, and performing like day one.

Please note: printed designs may fade over time in the dishwasher, and the lid should never be placed inside. Water can get trapped inside and cause damage.

A little care goes a long way.

Hoe maak ik mijn FLASKE goed schoon?

Voor een grondige reiniging en een fris gevoel gebruik je onze FLASKE cleaning tablets samen met de zachte borstel. Het kost je maar 15 minuten. Tabletje erin, even wachten, uitspoelen en je fles voelt weer als nieuw.

Geen nare geurtjes. Alleen pure, schone slokjes.

Hoe lang blijft een drankje warm of koud in een FLASKE?

Dat hangt af van het product, maar elke FLASKE is ontworpen om je drankje of maaltijd urenlang op precies de juiste temperatuur te houden:

Original Bottle en EVO Bottle 600 ml: tot 24 uur koud en 12 uur warm
EVO Cup 200 ml en EVO Tumbler 500 ml: tot 24 uur koud en 8 uur warm
Coffee Cup 380 ml: tot 12 uur koud en 6 uur warm
Food Pot 400 ml: tot 10 uur koud en 5 uur warm

Of je nu ijskoud water meeneemt, hete koffie of een warme lunch, je FLASKE houdt het moment precies zoals jij het wilt. De hele dag door. Elke dag opnieuw.
