How long does this flask keep drinks hot or cold ?
It keeps drinks hot for up to 12 hours and ice-cold for up to 24 hours thanks to its double-wall vacuum insulation.
Is the exterior made of real wood?
Yes. The outer shell is crafted from 100% natural, sustainably sourced organic bamboo, meaning every flask has a completely unique wood grain pattern.
Can I wash this bottle in the dishwasher?
No. To protect and preserve the natural bamboo exterior, this flask must be hand washed only and air dried. Do not submerge it in water for extended periods.
Is the flask safe to put in the microwave or freezer?
No. Due to the stainless steel interior and natural wood shell, it should never be placed in a microwave or freezer.
How do I use the built-in 2-in-1 tea infuser?
You can place loose tea leaves directly into the flask, pour hot water, and snap the mesh strainer into the top to filter the leaves as you drink. Alternatively, fill the basket with tea leaves or fruit slices and lower it into the water.
Does it fit into standard car cup holders?
Yes. The sleek, cylindrical design is engineered to fit perfectly into most standard vehicle cup holders and backpack side pockets.
What type of stainless steel is used?
The interior is made from premium, food-grade 304 (18/8) stainless steel, which is rust-resistant, BPA-free, and won't leave a metallic taste.
I heard bamboo drinkware can mold easily. How do I prevent this?
While the interior is completely non-porous stainless steel, the outer shell is 100% natural, real bamboo. To prevent mold:
Never submerge or soak the entire flask in a sink full of water.
After hand-washing the interior, immediately wipe down the bamboo exterior with a dry cloth.
Let the flask air dry completely in a well-ventilated space before screwing the lid back on.
Pro tip: Rubbing a drop of food-grade mineral oil onto the dry bamboo shell every few months keeps it hydrated and naturally moisture-resistant.
What should I do if a weird smell or stain develops inside?
If tea, coffee, or mouth bacteria build up in the steel crevices, simply swirl warm water with a tablespoon of baking soda or white vinegar inside the flask, scrub gently with a bottle brush, and rinse thoroughly.
Will the bamboo or metal leave a strange taste in my water?
Not at all. Bamboo straws or pure wooden cups can transfer taste, but this flask isolates your drink inside premium, non-reactive stainless steel. It will not alter flavors or leave a metallic or woody aftertaste.
Is the bamboo exterior treated with toxic chemicals?
No. The outer shell uses polished, natural bamboo. It is not treated with heavy industrial chemical varnishes or epoxies, making it safe to touch and environmentally responsible.
