I bought this cover because of the vibrancy of the colors (I accounted for the fact that frosted sleeves dull the colors of the covers), the beautiful pastel-like strokes within the design that contrast beautifully with the modern pattern. It's one of the most most beautiful covers I own and I've been a faithful client for several years.
I also own 3 covers of @artchiu's designs, that are all charming but this one is my favorite so far.
The black is deep and makes an exquisite contrast with the colors, which are even more beautiful in person, the gold in the name personalization looks beautiful (sticky noted for privacy).
The elastic makes a pretty contrast and is a nice touch from the more classic palette.
My only wish is for it to be available as a thin cover so I can match my half-planner to my 192-page notebook refill. I love to coordinate thin and regular-sized Mossery covers.
They're versatile, sturdy, customizable to one's liking, durable, useful and I import them from quite a distance because even with taxes and duties included I have yet to find a better replacement locally.
