Is this a washable, non-staining blue?

I'm not sure what you mean by "washable" as I wouldn't consider any ink washable. If you're asking whether this ink will stain your demonstrator pens (like the infamous Noodler's Bay State Blue), it won't. I've used this ink (my favorite blue by the way) in my TWSBI ECO, TWSBI 580, and Pilot Custom Heritage 92 and have never had a problem with staining. It is not permanent on paper and will smear/run if exposed to water. Hope this helps.

Is this a washable, non-staining blue?

I highly doubt that it is washable or nonstaining, although Ive never tested that. This brand of ink offers vibrant colors that are pretty intense. It's my favorite ink by far, but I'm guessing it's pretty permanent.

How long does a bottle last?

That depends on how much you write. The bottle is 50ML and your average cartridge converter holds 0.8ML so figure 1ML per fill on by the time you wipe off your nib after filling I fill my pen on about 1 or two times a day. I tend to write a fair amount every day so a bottle of ink last me around a month and a half your mileage will vary depending on pen paper writing style etc.

Best ink good value for money

Since it is a fountain pen ink, it isn’t water resistant, colour is a beautiful cerulean blue, seller is amazing for providing it at a discounted price.

Iroshizuku Kon-Peki

This was the most beautiful ink that I have ever used (I have used diamine, private reserve, waterman, Lamy, pelikan, namiki blue, etc inks, this was the best blue/turquoise ink shade). A bit costly due to international shipping and import charge but worth the price.Also, seller unbox japan shipped the ink directly from japan which was nice.

Nice ink, beautiful flow and the best thing is the shade of blue you have on paper. However, the ink is not water-resistant. Worth the price.

Konpeki

Kudos to the seller who sent it all the way from Japan at a decent price. It reached me in perfect condition.The ink comes in a nice box which depicts accurately the color of the ink within. The bottle is attractive and the ink color is exactly what you see on the strip of color on the label. It's a nice deep blue, like the deep ocean. I feel this color can be used for official purposes as its not outrageous.

Freeflowing great looking color.

This beautiful color. It has no hint of Green unlike other Turquoise blue inks. Its very subtle color and flows so well. Amazed by this ink.I have Lamy turquoise ink as well, which runs dry in most of my fountain pens.Comes in a beautiful hand blown glass bottle.Unlike this. Cost is the only factor which goes against this ink.
