Very Handy for Writing and EDC!
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.

Moderately Effective, Not Worth The Price
Doesn't hold much. The hand strap on the back as it's impossible to get it to a point where it may be tight around a large, adult hand. Unsure how well the elastic loops will safely retain pens over time.
