Poisonous Plants 18 oz Steel Bottle
Fill this Poisonous Plants Vacuum Flask with your favorite elixir so you can enjoy it at your own pace. Your hot tea or cold kombucha will be ready whenever you are, so you can feel free to get lost in your studies, plans, or walk in the woods.
With a textured design for a unique tactile experience, this flask will keep your drink hot or cold until you're ready to enjoy it.
Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time.
Simply stated, vacuums make great thermal insulation!

Frequently Asked Questions
Will Buy Again!
Even though I had a small issue with the product I ordered, there was a swift replacement and they were very kind about the entire situation. The quality is unmatched and the designs are amazing!
My favorite water bottle ever
I love this water bottle. I use it every day. It’s so beautiful. And the water just seems to taste better in this water bottle?? Perhaps it’s a personal bias. Would need to conduct double blind study to confirm hypothesis
It hold the heat perfectly
Beautiful water bottle with one drawback
These water bottles are so awesome, unique and beautiful. The only downside is when you take the cap off it often drips water on you. It’s annoying, but manageable.
Beautiful bottle and it also insulated as advertised.
Love this flask.
I love this beautiful bottle. Keeps water cold all day.
Poisonous Plants Stainless Steel Vacuum Flask
Lovely as always. I always get great items.
Cane Friendly and Quality!
I walk with a cane pretty often. Traditional mugs and travel mugs with no handle can be cumbersome and usually take up your whole hand. This mug, however, I can thread a finger or two through and still grab a plate, a book, even my uke. Not only does it make my life easier, but I was blown away by the quality! The print is GORGEOUS and I can even read the tiny print for the plant IDs. It's textured nicely, not flat, so it's secure to grip even when wet from washing. The handle is sturdy and gives leverage to open the right seal because this does close nice and tightly. It keeps my coffee HOT hot for a good long while, too. I honestly love everything about it and would recommend it highly.
As always, their products are top notch! The handle on the lid is a game changer for me. It's the perfect size, keeps stuff perfectly chilled and the exterior designs have held up to repeated washings.
