Bright BLUE in my EDC Safari Graphite. (Chou Kuro in the Charcoal)

This is a very lovely, rich blue shade. Almost leans a little teensy bit to the purple side in bright lighting. I'm using it in a .3 Platinum Preppy with a piston converter, and didn't notice the staining issues that I'm reading about in the other reviews. Not yet, anyway! With a fine point, I don't notice it being too wet as I'm writing; and, there's no smudging in my daily journal. While I have a massive collection of blue inks, I'd say this probably makes my Top 10 Blues. This is actually the color I was looking for to put in my Metropolitan Violet Leopard medium point... (attached photo shows M05 on the pen barrel, but it has a .3 nib in it)

This is a great blue color. However I find that it seems a little runny. The letters bleed when I write with it but works best with thick paper.

This blue reminds me of the dark blue I’ve seen in the ocean from high above in an airplane. This blue looks like it will swallow you whole but in the best way possible.

Put this in a Jinhao fine nib, flows very wet. Color is wonderful, but it feathers on my Kokuyo paper, which is supposed to be at least ok for fountain pens. Also super showthrough-y, even compared to inks with similar saturation levels. Would bleed through for nothing if I wrote slower or used a wider nib.

This is a vibrant blue that really stands out. It flows well and drys quickly. The one draw back is that it does stain and should have a dedicated pen. However if you are willing to do that it is well worth it!. After all ink stained fingers are a proud mark for a fountain pen enthusiast!

This ink is very bright and I really enjoy writing with it. It makes me happy to see the bright blue colour on paper.

The order worked out great. Everything was as advertised and the delivery went smoothly.

Mostly great! Beautiful. I refilled a namiki cartridge rather than using the CON-B converter, out of sheer laziness, and put it in my Pilot Metropolitan, my first FP in almost 20 years. I am torn between never using this ink again, or dedicating this clashing turquoise pen for this gorgeous blue ink. I wish the ink description came with a little warning!Staining: HIGHBest paper to use? Not sure yet. Varying levels of Ghosting on everything.Pros: it made my scratchy fine point Pilot pen fun to write with. Can an ink make a pen give less feedback? Cons: stained fingers, nails, sink, a little afraid to open the sample to fill up again.

I have it inked up in a blue Jinhao 51A and so far so good. No drying out issues at all. The color is electric. I am apprehensive about the staining quality of the ink but so far no issues with that either.

Definitely a nice color but the staining and associated clean-up is just not worth the effort to me. I was able to clean my pen but also had to scrub my sink, fingers, etc.

Vibrant!!!

I thought I had already found my favorite ink, then I tried a sample of Noodler's Baystate Blue. I bought a bottle right away.

I truly love Noodler's Baystate Blue. It's like a 'neon' blue that has great contrast, but really grabs attention. I use it in a dedicated Platinum Preppy with a medium nib and it never gives me trouble. I use it while journaling for writings I'll want to be able to later find easily and I write all checks with it. Perfectly waterproof. I've had bank tellers ask me 'what kind of pen' I'm using and I always enjoy telling people that I use a fountain pen with Noodler's inks. I know there are negative reviews about its staining properties, but bleach takes care of Baystate Blue and having a dedicated pen means it's a non-issue. (Lucky for me, I also love lightweight and cheap, Preppy pens.)

Yes, the ink is difficult to clean up. But it is worth the bother. I wanted a bullet-proof blue and BSB delivered. Now I can address envelopes with confidence the my letters will go to the right address. For me, this ink is a must-have for my trove of great inks.

Really like the color

Ah, the infamous Baystate Blue. As a newbie to fountain pens, I was scared but intrigued by this ink. I figured a sample is a good cost effective way to try this ink without much risk to my wallet or my countertops. Glad I bought it! I took some likely ridiculous precautions before I opened the sample- a layer of tinfoil with paper towels over it, pre-torn paper towel pieces to mop up any mistakes and errant drips, and disposable gloves to protect my hands. I also treated the vial like it was full of Ebola. Lol. Turns out everything was unnecessary except for the pre-torn paper towels. After a quick dip with a pen and a sample of writing, I fell in love and inked the pen up fully. And fell even harder for for this ink. It's stunning. As others have said, it practically glows off the page but in an attractive way that is still easy for me to read. Now I'm writing this review but after this will be heading straight for the full size listing to buy one. This ink is that freaking beautiful.

I like the color. It is nice to write with, flows well through my fine and extra fine nibs. Looking good, flow and wetness are important in the ink I use and Noodler's Baystate Blue fits right in for me.

Highly pigmented ink! Its a very nice color.

I have been sampling four blue inks to determine a blue ink to use. I am testing this in a Platinum Preppy with a fine point. I like the way the ink goes on paper, but the color is a bit bright for my tastes for everyday use. This seems to be a very good ink none the less.

Beautiful, deep, vibrant purple like ink that only cleans with bleach. It is the worst stainer in the world. Do not use with valuable pens

I have not used the item yet. Having said that, the entire process was outstanding from exceptional web-site interaction, ease of ordering, to delivery and receipt in a timely manner - just the standard Goulet level of excellence!

At first, I really really liked this ink. The blue is incredible. Almost neon jumping off the paper. I found it wrote really well on almost all papers (anywhere from rhodia to cheap composition book paper). It did have some show-through with cheaper paper so be wary. It was a little dry in my EF compared to some other inks. Dries really fast (> 2-3 sec on most paper), is moderately waterproof, and has very little feathering. The worst part about this ink is cleaning out the pen. My TWSBI ECO T had a blue stain/tint in the section and the barrel. Also, there was some precipitate or some kind of particles in the ink section of the barrel. It ended up taking some light rubbing alcohol and a lot of water flushes to get it clean. Be warned that this is a great ink for color and writing, but cleaning takes some elbow grease.

Yikes!! Beautiful color, but what a mess. It stained my fingers, my sink, and my pen nib & converter. Thought I'd never get my pen clean. I'm glad I just bought a sample.

Brilliant, electric blue color - the most attention-grabbing blue I've ever used.Could be tiring to read long passages written with this ink.

This really is a great blue. Now I have to decide what pen to use with it.

I ordered a selection of water resistant inks to try out for my professional use. Bay State blue is my favorite, due to the color, however, on my Leuchttrurm journal, I get terrible bleed. I'll be sticking with Liberty's Elysium for now.

The color itself of the ink is amazing, as others have said. However, I tried the ink in a couple of my fountain pens (Pilot Vanishing Point, F nib; Platinum Century #3776, F nib) and ran into feathering problems. I typically have a small, tight handwriting style, so ink that spreads is an issue for me. I suppose if I wrote larger or only used very high quality paper, that concern could be mitigated. However, due to this, as well as the required maintenance for cleaning pens with this particular ink, I won't be using it. My inks of choice will remain Noodlers' Blue and Diamine Blue Velvet.

Very, VERY vibrant shade of blue. Looks amazing on paper.Unfortunately, it occasionally feathers, even on Rhodia 80g paper. I'm still going to keep using it.
