"I have purchased 5 at least. 4 I use and other passed on to family. My fountain pens are protected whether they are beginner level or higher. I know which way is up be for opening due to the zipper pull cord. Very handy. Four pockets plus space for a little more. I organize my pens based on current projects and use. Multiple quartos help with this. I can pick up the quarto and the pens I need are inside and ready to go." - David H.

"I bought this for a birthday present for a friend of mine who collects fountain pens. He had commented that the perfect pen case would hold 4 pens so you could have Red, Black, Blue and Green ink colors. He liked the design with the pens on one side sliding in from the top and on the other side from the bottom. Also the fact they holders are spaced such that the case closes and is the thickness of one pen." - Mark C.

"I have been carrying various fountain pens around in individual pen sleeves, and this made it easier to carry four. Rugged, sleek, easy to open and close. The pens seem very safe and secure. I really liked this idea of this compact case, and I took a chance. It was better than I had expected." - Jake W.

"I have purchased a few pen pouches however; the Quattro by is the best and most protective of my fountain pens. The slots are offset and well padded, and the whole case is well padded too. If necessary, I could add one more pen. Quattro is a fantabulous pen pouch!!" - Oliver Y.

"I have several fountain pens that I use for writing. This was the perfect carrier for them. And, I love that it’s vegan and no animals were used to make this product!" - Bertie W.

"I'm a fountain pen geek, and have been looking for the perfect storage system. When I saw this I knew I needed it. I had never heard of the brand before, but this thing is immaculate... in design, construction, materials, everything. Well. Done. You. Of course when I got it, I started realizing the many other ways this would be useful. Soooooo it won't be long before I order another one." - Sam K.

"This tool roll is sturdy, thoughtfully designed, and is an absolute beauty on top of that. I currently have 10 fountain pens/pens/pencils and they all fit without a problem. This was a fantastic purchase." - Eduardo V.

"I have been setting up this pen case to hold fountain pens, pencil sets and lastly a hold all for outdoor or urban sketching essentials. It is a fit for all my passions! I guess I need three more! It looks like it will have a long life. It is extremely well built and designed." - Maggie

"I had wanted this to use as a cover for a Hobonichi Cousin Avec. Even better, I can incorporate other notebooks using the strings. I stocked up on the notebook refills that use the glorious Tomoe River paper for us fountain pen lovers. The Field Journal is well constructed and so versatile. You can truly tailor it to meet your needs. This goes with me everywhere!" - Darrell M.

"This product is outstanding! It's well thought out and checks all of the boxes for me. I will never travel without it. Not only does it hold multiple notebooks made of the fountain pen friendly Tomoe River paper, but there are pockets galore for additional storage. And the exterior is made of quite a sturdy material which I love. The folks at Lochby have it one out of the park on this one!" - Richard T.

"The field journal is perfect for my needs. It's lightweight but sturdy and well sewn. Military strong. I have three A5 notebooks in there and so glad that I ordered more of your great Tomoe River refills as it is such a great quality paper. I have a passport notebook in there, three A5, index cards, washi tape on an old credit card, full blotter sheet, more goodies to pack and of course my fountain pen that fits perfectly secure. I am so happy with this purchase." - Martha L.

"This is by far the best product I have used. I can't say enough good things about it. It fits plenty of notebooks for all the different subjects I need with room to spare. The pen loop holds a Karas fountain pen (which is huge) with no problem. The closure strap is adjustable which is really helpful as I take out notebooks when I need to. The paper in the notebooks is awesome quality, too. Overall, amazing product. I would definitely recommend to anyone." - Daniel
