Iroshizuku has some very well-behaved inks, and Ajisai is no different. It's a wet ink in my opinion, but I really like that - and it dries very quickly, which is necessary because (although I'm right-handed) I drag my hand across my writing so if the ink doesn't dry fast, my hand will get ink all over the side of it. This ink always stays either in my pen or on the page where I want it! And it really is a gorgeous color - currently one of my top two. I'll be buying another bottle for sure.

This is my favorite ink I own (and most expensive) but the color just pops off the page and the way the ink flows is perfect. Love love love the color.

This is such a pretty shade of blue. It's a little darker that I thought it would be. But when it dries down, it does remind me of the hydrangea flower colors, which is cool.

Beautiful color

I really love this ink. I haven't used it a great deal yet t but I'm sure it has had a lot of good publicity. I adore the color. I think I need to dedicate one pen to it so I can really see its full ability.

This is exactly the color I was looking for, and after trying a sample, I had to have it. And thanks to Goulet for the great customer service.My ratings on other attributes may not be totally accurate as I'm all about the color!

Color is wonderful... very lovely.

I was eager to try this color, because in part.... I love Hydrangeas! The ink however was somewhat disappointing. It goes on quite dark, but after a few seconds on the page it really starts to fade out. It's probably one of the lightest blue's that I have in my collection. I have to say, that I've inked my pens with it only once or twice. It's an Iroshizuku like product, and like all others, it's well behaved with any pen.

I bought this ink a few weeks ago. I really love the color. It has a ton of depth to it. While it has violet tones to it, it still reads as blue. It is very reminiscent of the hydrangeas it is name for. It is of the same quality as the entire iroshizuku line of inks.

Several years ago, I found some old letters that my grandparents had written to each other when The War (WWII) required my grandfather to travel far from home on business. This ink is the same color of ink as I saw on those faded old love letters.Maybe for that reason, Aji-sai strikes me a refined, elegant, timeless ink color. Be warned, though that this is not a saturated ink. Instead, it's a soft purplish blue, like the hydrangea flowers my grandmother used to grow. That makes it an ideal ink for love letters, and for anything you want to write that speaks of elegance, poise, good manners or lingering, beloved memories. My mother and I recently started putting old photos in scrapbooks, and this ink not only looks terrific on the cream-colored pages, but also adds the right vintage touch to caption photos in our collection that are 120 years old or more.One of the amusing things about Aji-sai is that it's almost the same color as the old mimeograph ink from when I was in school. It's so close that when I had to walk away mid-letter while using Asi-sai, I came back to see the ink on the page and automatically lifted the paper to my nose to get a whiff of mimeograph smell, only to be sadly disappointed. I guess I just gave my age away with that one, but oh well.

This is more of a purple-tinted blue than I was hoping for. When I asked other people whether it was blue or purple, they all said blue. In real life, it's grayer than on my screen. I think in a broader nib than my left-handed Pelikano Jr, it would shade nicely. It's very pretty, but I'm not sure it's worth the money.

I have been using other Iroshizuku inks and as always, the Ajisai did not disappoint. Well behaved, excellent color saturation and shading, soooo smooth and so easy to clean. Iros are my favorite inks! I'll probably keep collecting all the colors.

nice - in retrospect i should have gone for one of the darker inks as it's quite pale even with a broad point but lays well on all paper, smooth and flows easily. very happy.

I purchased a sample of this lovely ink. I currently have it in my new TWSBI 580 EF, it writes very smooth, so far I have only used this ink in my TWSBI, I want to see how other inks work with this pen, which I love, love, love. I do not think the color is too light, on the Rhodia ivory paper it is a lovely purple shade, on white it looks slightly bluer but still definitely purple. I may choose this as my blue(purple) ink. Pricey but it may be worth the cost.

I'm disappointed at how washed out this color is- mine is a pale blue-purple, nowhere near as vibrant as the swatch. Pretty color, dries very quickly, but I don't see myself buying a whole bottle.

Very similar to Bleu Myosotis but with a touch more blue. Could be a fave color for me.

I purchased a sample of this ink, and what I received bears little resemblance to what is on the screen. My Ajisai sample is a soft, almost pastel purple with a hint of blue. It's pretty, but not what I was expecting. My 25 other samples are quite close to Goulet's swabs, so I don't think it's a case of monitor color settings.

I loaded this into a wet writing Pelikan M400, and thought I had forgotten to dry it. After several pages, it was still the light/faded purple it started as. This ink does look like a color of hydrangea, right down to the softness. The color does not match the swab, and does not match any of the other swabs/samples I've seen elswhere. If you want a pastel purple-shifted blue should work for you. If you want something with more intensity, suggest Asa-Gao.

I sampled several of the Iroshizuku blues, and I like this one best. It's fast-drying and I keep it in a stubbed Levenger True Writer. One surprise--it's a stand-out color for marking up manuscripts.

This is an exceptional blue which is more reminiscent of the Mediterranean than anything. I've purchased three different shades of Iroshizuku from BrIan and Rachel Goulet and though this stuff is pretty expensive, this is some of the best ink I've ever used. Incidentally, the Goulet's offer great service. My package came in three days and it was extremely well wrapped to protect it during shipping.

It takes me some time, but my blue is this blue ... I guess

I prefer Kon-peki, Asa-gao, or Tsuki-yo from the Iroshizuku line of ink by Pilot / Namiki. Too plain for the price tag!

All the Iroshizuku inks are excellent - vibrant and free-flowing - but the range of blues is especially good.

All of the Pilot Iroshizuku inks I have tried have amazing flow, and the Ajisai is no exception.

The bottle is gorgeous. Color is tad dull. Given the past reviews i have heard about this range, i was expecting a brighter color.

Better then the asa-gao deper blue but I was looking for what Mr. Goulet had in his pilot custom pen and must have mixed this one with the one he had liked. next time I'll order that to try.

Blue seems to be one of the most traditional colors and there are a lot available. The ink behaves well and is totaly ok. But! There are a lot of other inks for less price that are so alike. I have Edelstein Sapphire and they are really similar, for less price. Hence the 4 star rating.

I originally ordered a sample of this lovely color and like it so much I decided to bite the bullet and order a bottle. Even though it is on the pricy side it has such a wonderful feel when writing with this ink and I absolutely love the color. Kudos to the Goulet Pen people as their customer service is excellent and friendly. I love the fact they use different pens and ink's when writing notes on the invoices that give us an opportunity to see different pen's, nib's and inks that we don't own. Keep up the good work. The only time I order from elsewhere is when you don't have what I am looking for, as example, the Sailor 1911 pen purchased as a gift for my husband as a graduation gift when he earned his Masters.
