Don Fisher Logo

Don Fisher loves sailing the seven seas in search of nice things. He spends his time fishing all the Bonitos he can.

They are well-known for their Bonitos which are all hand made with the highest quality materials and are fresh and ready to use. Also, their inside is fleshy and full of fishbones, completely irresistible.

Award-winning design. People loves it, judges love it too.

There is more than meets the eye when it comes to our award-winning design. Besides the super customisable feature loved by many, we have some extra little tricks that make it even more lovable.

We believe progression better than perfection.

We say no to almost 50 prototypes. The Nº1  Classic Series was born out of relentless rejections and continuous improvements.


Another level of detail

A special technique Spot UV was used to enhance the visual and tactility of the cover design. Take a look under the light, you’ll see a shinny, glossy watery look, particularly on the bubbles.

Don’t judge the book by its cover. Because it is detachable. The paper? Refillable.

It is weird we want you to spend less. But the whole idea of our Classic Series Notebook is to reduce wastage. Made only when it is necessary so we don’t have dead stock piling up in our storeroom. A detachable cover is the answer to it.

Adjustable pen loop. For all pen sizes. No discrimination.

Pen loops on a notebook is not particularly revolutionary. Well, we make it a bit more delightful to use, just like your belt — adjustable. So, you can fit in any pen and pencil you have.

Interchangeable ribbon markers. Why not? Make life less of a bore.

Ribbon markers have been bothering us for quite some time. Why can’t it be colourful? What if I have more pages I need to bookmark? So, we have made it interchangeable, up to 4 in a book. Don’t call it a gimmick, it is much more useful than you would think.

To protect your book, to make your gift looks totally cool and to safe keep your finished notebook. That’s a steal. 

It’s not hard to understand why we do that. Reduce, reuse and in the same time remain the the pleasure of unboxing for your instagram post. Our reversible and reusable packaging is the answer to that! Remember to tag us #anatomyco!

Opps. We almost forget to brag about our paper. Bla, bla, bla…

We chose high-quality insert papers for your notebook. It is soft in texture, cream in colour, smooth to the touch, and most importantly, fountain pen, gel ink pen and ballpoint pen friendly. Through meticulous testing, it has proven to excel in its writing performance with no visible signs of bleeding.
