It is water resistant, and maybe waterproof if you wait long enough and let the layers of waterpaint or ink paint dry inbetween layers. If you try to paint 20minutes after you put it down with water paint it has a 50% chance of smearing if you use to much water or you had used to much ink when doing line work.My only problem was using this with my glass dip pen. It’s to thick to come off the glass dip pen correctly (For my pen at least every glass pen is different) So I had to dilute my ink with water to get it to flow somewhat correctly. So I can’t just use it right out the bottle I need to find the right consistency for my dip pen for it to flow and sometimes I get it a little to thin. I do like it, I’ll use up my 2 oz because it is indeed good ink.pros-black before thinning out so you can get an array of blacks to grays for ink drawings.it is in fact water resistant. -it’s notit is sealed with a tab so it doesn’t spill out when you recieve it.cons-can be to thick for glass dip pens -completely to thickif using a glass dip pen you will need a brush (i use a eyeshadow make up brush) to clean the crevices of your glass pen because this ink loves to holy snickers stick in the grooves.if you forget to buy the cleaner or your out of it, just use dish soap and vinegar mixer, it cleans your hands and glass dip pen pretty well. The only reason i’m giving this 4 stars is because of I have to spend 10 minutes trying to get the right consistency for a glass dip pen. You get pretty good ink for the price you pay. Just be aware this ink doesn’t seem to work with glass pens well unless you dilute it. I don’t own a metal dip pen so I don’t know if it works well with the metal onesedit: For the love of everything holy and unholy, do not use this with glass pens, don’t even use it for anything but brush stuff. What I thought was water resistant is definately not. ohhh the water smudges when I went back some month old art I made with this ink to add a bit of that cool ink with gold speckles in it that came with my glass pen. If you want to use this ink, use it with their brand name dip pens. I’ll still give it 4 stars since it did not say it was for glass dip pens. but it is NOT WATER PROOF OR WATER RESISTANT don’t ruin your artwork like me [...]
