Study your cardiac rhythms while keeping hydrated! Nicer looking than an EKG pocket guide, this Heartbeat Flask is both functional and aesthetic. Fill it with ice cold water and take it to the gym for your cardio workout, or top it off with herbal tea for a long night shift in the cardiac ward.
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.
Designed in USA
BPA-Free
Compostable Packaging
Carbon Neutral Shipping
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!

Ancient Egypt and stationery? Count me in!
Along with dinosaurs, ancient Egypt has been a passion since I was a little kid. And as a journaler, this was a must have. Beautiful to decorate my spreads.

wonderfull bag

Beautiful pattern
I am a sucker for mushrooms. I find them so pretty and magical, and very very important for the ecossystem. There is something mesmerizing about them. And so I had to get one of these pretty tote bags, but it was hard to choose one. I went or the one that was more Autumny, and perhaps in the future I'll get another tote bag with mushrooms. The material is quite good and the print is lovely.

These Notebooks Are Superb!
Highly recommended. Very good value. Well bound. Good quality cover and paper. Prompt Delivery. These notebooks are just great - exactly the same engineering paper I used at university over 40 years ago! I also like very much the “thematic” selection options. I ordered two books from four engineering themes. My wife is a neurologist, and I also ordered a number of notebooks and other materials for her.
Good product
Really neat, simple and motivates me to be somewhat organized!
