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.

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!
