So I can only say thumbs up. The book fulfills all expectations. It is tied and you can write well in it with pencil or pen. Today we have the notebook undergo a tough test. 24 hours in water is no problem for the paper. Even writing underwater works still outstanding. After 24 hours in the water everything is 100% readable and even after drying, the paper is not curled, and also does not stick more together !!!
All in all, full marks to the book. And for the price, it can be more than excellent. Compared to other products of this type is really cheap.
