Dear Alain.
Thank you for your review.
Yes, you are correct, this notebook has an unusual construction with two covers. The inside booklet is wired stiched in three places, in an unusual way. More on the binding technique at the end of the review

This shop uses genuine Tomoe River paper sourced directly from Tomoegawa. We are, in fact, the only company from Europe with an official Tomoegawa branding licence, so there is zero doubt about the paper. But you are right, the Tomoe paper used in this book is thicker than the usual 52gsm Tomoe. This book is made with the 68gsm version of Tomoe, the 68gsm version of Tomoe is our best seller. Very few people know, but there is even an 80gsm version of Tomoe, we have samples but have never used it as it's not fountain pen friendly.

This shops uses (Oct 2021) the following Tomoe:
- All Tomoe River 68gsm products: OLD Tomoe, manufactured at Tomoegawa factory Machine number 6, before the summer of 2020. We managed to purchase the last batch before production was moved to a new machine.
- All Tomoe River 52gsm products: NEW Tomoe, manufactured at Tomoegawa factory Machine number 9, after the summer of 2020. Machine number 9 was shut down on Sept 2021, so the future of Tomoe is uncertain.

Going back to the binding. All our notebooks are wired stiched and the spine is formed to ensure the book stays flat, almost like thread stitching, functionally speaking it's almost the same. Our TN Inserts are traditionally stitched and notebooks with elastics have a mix construction. We do it this way to ensure variations, the shop has 12,220 possible combinations; if we used thread stitching we would only be able to produce 1% of all those combinations. We have decided to focus on increasing personalizations and variations as much as possible because the perfect notebook is different for everyone. At the moment no thread stitching equipment in the market can provide such flexibility. The moment it does, we will change the equipment.
