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!

It's perfect. My shaker bottle spring fits inside if I twist the girth down a bit, so my protein shake no longer has microplastics chipped from my old shaker bottle.
Beautiful
Great design....now all they need to do is offer one with their classic cell biology design.

Such a fun journal cover, and I love that there’s matching washi tape.
I love the vintage-y feel of the illustrations on the Whales & Seals journal cover. Whats not to love about some marine charismatic megafauna?
The Ocean Planet journal is gorgeous, i love the moody feel and finding all of the lityle details.
I love these journals. They really do lay flat, and they’re the perfect size. The dinosaur skeletons are awesome and i get compliments everywhere i take it.
Grid pad but better
Perfect for lab and engineering notes, this bound version of a standard grid pad is my go-to notebook for work! Well-made to survive wear and tear. This is my second one but certainly not my last.
Perfect for Myself and as a Gift!
I bought two of these after deciding to buy one as a gift for someone. I'd been wanting one of my own for ages and decided to get two after looking for a gift. Both mugs look great! They were packaged very securely, and shipping was super fast. Definitely going to order more from here.
Beautiful colors looks well made. Gave as a gift. She loved it.

grad gift
Got this for a med school grad heading into cardiology - it is a great size, will hold up well, keep the coffee warm, love the graphics. After some fiddling, the top now fits firmly.
