Since I have a large collection of regular notebooks, my attention has now turned to original pieces that could bring something new or different to my collection.
I discovered this model and thought it could be great as a one piece transportable notebook. Mark’s Inc was kind enough to send me one for a review (disclaimer: I have no specific connection with them) and so here it is.
You can find additional information on their website : http://www.marks.jp/en/product/storage_it.html
And purchase it from Amazon.com : https://www.amazon.com/MARKSTYLE-TOKYO-STORAGE-Notebook-Orange/dp/B00IID10KK
