It's a gift
Got one last year for the grand niece and now one for the grand nephew's graduation. I also put some cash inside along with the sunglasses he left at my cottage. His sister loved hers, I'm sure he will like his.

Beautiful Book
It is perfect. I love the texture, the cover, and the black paper. It is exactly what I needed to journal and is significantly better than traditional spiral bound notebook.
I love my water bottle so much! I get so many compliments on it!
Love it!
This is a gift and she's gonna love it.
A great gift
My product arrived on time and looks great. I got it as a gift for a friend who is an earth scientist and it was well received.
I love it!
Fantastic quality material, and the print looks lovely. I use it at my desk in the office now and it really brightened up the space. I would definitely order from here again, lots of interesting mouse pad designs to choose from :)
Great for organizing our car
We bought a handful of these in different patterns to organize the front of our car, and they're perfect. If anyone owns a 2024 HR-V, these fit perfectly in both the glove box and the center console. We also have another that we use in our safe deposit box. These little bags are endlessly handy!
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.
