So great at keeping a pencil or pen or pen-brush with a sketchbook or notebook. I bought a pack of two previously and liked them so much I bought another pack!I have it on a 9" tall sketchbook with hard cover and it's perfect. The zippered pouch is around 8". It's not tight, but stays on. Can easily stretch to 12"--not sure how much bigger...

I like the colors. The red and blue colors are nice, kind of a smoky blue and an earthy red. The case is smooth and soft. The elastic fits on a small hardcover book, which is great. I thought it might be too big, but it isn't. Just large enough to fit a pen and slim highlighter, or a couple of pens/pencils. Zips smoothly and so far is serving its purpose.

Using one on a composition notebook, and it travels well and holds three or four pens (I have two Frixion Clickers and a Frixion highlighter, and it's a tight squeeze). I don't know how well the elastic will hold up over time, but so far, so good, and I've taken it on several trips. Even if the elastic goes, it'll be good for a pen case for my purse.

Overall really good idea and well executed; wish elastic was a little more sturdy but so far is holding up fine

So far product has been working as it should but I have only had it for a week. I'd like more variety in colors but like I said it's been working well.

I didn’t know how they would work out, but now I love them! Good quality, but I could see how the elastic could stretch out over time.

Just what I need to storage my apple pen. Now I’m not afraid to lose it. My husband use it for his Microsoft surface.

These are great attached to the cover of my journals. Keeps a pen and pencil handy for when the mood strikes.
