This water bottle is really beautiful.
I recently gifted this to my chair, which is an ornithologist and she liked it. Is so pretty and sturdy.

Great quality
Beautiful, nerdy and good quality.
Very cool book, but when I purchased there was no offer to add on the pens I’d need to write in it. That struck me as odd. Then, only after I’d purchased, they hit me up for add-ons, including the pens that I would have bought earlier, had I only known that they sold them!
best coffee cups
each cup is beautiful inside & out & such an ecclectic collection of perfectly sized cups
When I bought these pens, the pen nerd in me was thinking "Opaque colored pens?? Nice!"
When I saw the names, the science nerd in me was thinking "Names based on flame colors from burning elemental salts?? NICE!"
It wasn't until I got them in my hands and saw them that the LGBT nerd in me was thinking "And it's our flag!? NIIIIIICE!!!"
I really like the product, and the causes the company stands for.

Such a cool cup, I love it. If it had a misprint I didn’t even notice.
It’s awesome! Built great and the graphics are great too. Didn’t scratch off at all after a week of use so that’s a good sign.
