Love the color! Cannot wait to use it more than the swatching I did.

Gruene Cactus is a beautiful color. Writes well in the Preppy pen I bought for my son. Will be buying more soon.

I used this in a Jinhao x750. It is a nice green and flows well in this pen. It does take longer than usual to dry.

I love the color.

I got a sample of this after getting a recommendation on Goulet's Instagram page and I really love it! It's the perfect green in my opinion

I absolutely love the color of this ink. I used it as more of a highlighter for my notes but had to stop using it all together due to its dry time. I see some people say in their reviews that it has a decent dry time, but even using a fine point with Rhodia paper has me waiting 5+ minutes and still not completely drying. I wonder if its just the batch I got. Smooth writing, beautiful color, but I just cant get over the dry time for my purposes.

This green is a little more 'pungent' looking than the photo, think a little more lime-chartreuse. Its a great color, but the reason it is four stars is that it feathers so easily. Any nibs above a fine (or Japanese Medium) and it feathers. I wouldn't use this for journaling, writing letters, or even a daily ink so I'm glad I only bought a sample. I really can only see a color like this being used as an 'art ink'.

I got this sample with the random 8 pack from the First Time kit. I really like this ink. It was the reason I considered using green for everyday use. It is a little brighter than I was looking for but flows very well. It is slightly subdued and would make a great daily use ink. It is not too bright but just bright enough to be fun.

My intention was to get an ink that matched the color green in my old Pilot G2 (prior to my switch to fountain pens). This ink fits that bill perfectly. I love the shading and flow - an all around good behaving ink.

Used it for all my Christmas and Envelopes. Worked good on the cards even though it was not the best paper.

This is my favorite green - I use it all the time. It does take quite a while to dry, even on cheap paper - but it's worth it.

This is about the color I think of when I hear Kelly Green. A stong green color with a very slight tinge of blue to it but no black tones.

This is a beautiful green that reminds me of the Emerald City in the Wizard of Oz. The ink shades nicely and I will eventually purchase a full bottle.

Bought a sample to try, and am waiting for a bottle in my next order. This is my go-to green now.

I tried this as part of the medium greens sampler from here. This was the lightest of the greens and to me looked like it was washed out more than just lighter in color. It's too bad the color didn't thrill me as it performed as well in terms of feather resistance and shading as much more expensive inks.

This ink works quite well. The Green color stands out nicely on white paper, and makes notes more interesting to read and write since they are not black and blue. It does bleep through some papers, so be weary on whether or not you plan to write on the back of your paper.

This is a nice bright green ink. It brightens my mood when I write with it.

This is a perfect green. Not to dark or light, and has a touch of vibrancy to it. Perfect for proofing my magazine.

But writing with this ink is delightful. Very green, very well behaved. I love it.Side note, did y'all know that green is the preferred color for proofreaders and in journalism school, you are taught to use green pens for writing on copy? Crazy!

This is my favorite green ink. I spent hours on Fountain Pen Network reading ink reviews to try to find the perfect green. I ordered this one after much deliberation, and I was not disappointed. This ink is a beautiful color, and behaves very well on good paper. This is going to be a permanent staple in my ink rotation.

This ink changed my opinion on black-only. Writes much lighter than I was hoping, but it is very light emerald looking as it dries. Nice ink, love the samples.

This ink really soaks through paper. I need to use good paper like the Clairfontaine notebook I purchased or else a Red and Black notebook.

A bright green! I purchased this ink expressly to mix it, which I did. I knew it would be a bright green (and it is), a bit brighter and yellower than crayola crayon green. It's a nice color, but a bit bright for me. It is well behaved. I mixed the bottle of Gruene Cactus with about 1/4 bottle of Noodler's Black and it made a delightful dark rich green that is very well behaved.

A very nice ink that has great shading with wet pens. I decided to try it after my last Goulet Pens order came with the usual hand written message on the invoice. DAMN YOU GOULETPENS!!!, how could I resist but to order.
