Waterproof perfect as travel fountain pen case
Awesome very small size waterproof bag. Purchased to use as a travel case for my fountain pens and ink (just in case). Although I have never had an ink accident, I wanted something compact enough to use in a small cross body bag without wasting space for the sake of an extra measure of assurance I wouldn't end up wearing my ink.
NOTE, I do not use the disposable ink cartridges only adapters or dropper fill. So if I were to experience an ink mishap it would be more than just a tiny amount of permanent ink.
The bag seems to be very well made. It is exactly as described, the only thing that may not be obvious is that the material is quite robust and there is no real give. So it works perfectly as a pencase and for a passport or smaller notebook. I would note recommend using it for something thick or round, like an apple or a larger size bottle of ink. However for a syringe full of ink along with half a dozen fountain pens it's superb!
Will definitely buy again when need arises.
This would also make for a great safe case for a smaller phone. However current flagship phones will not fit through the limiting zipper length.
A future improvement of having the zipper go just around the corner to allow full length access would be an awesome improvement which would then be perfect for a newer model cell phone.

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.
