It does exactly what I need it to! It fits well on my A5 notebook and has just enough room in the pouch for a small knife, a lighter, a small flashlight, and some pens! It's a perfect edc carry for anyone who likes to have a small notebook on hand! Also the quality is really amazing and I have no doubts that this handy little pouch will last a long time.
