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.

Good quality - not very useful
Good quality utility pouch, downside is no recent phones will fit in this pouch as shown and the strap on the back is useless. Would've returned it but liked that it is waterproof and can hold thin items. Not the best value for the money if you wanted to protect a phone. Zipper is very sturdy. Too thin to be functional.
