The Sari notebooks are available in different sizes. The book cover is covered with the fabric of Saris, so each book is individual in pattern and color. Handmade paper is used, in which petals, grasses, straw, etc. are partially incorporated. The paper is made from natural materials without the addition of chemicals. The paper is more absorbent than industrially produced paper, so the use of fountain pens is not optimal. Ballpoint pens or rollerball pens can be used without any problems.
