Diamine Oxblood Ink Review: The Surprise Ink!

So I want to start this review off by saying that I am not 100% that this is the correct ink, I may be wrong and had the wrong assumptions about this ink..We’ll see. I recently received from a five pack deal on Massdrop and although the bottle says “Diamine Oxblood”.. it may actually be “Diamine Rustic Brown”? Anyways.. my reviews are really just me documenting my journey and explorations in the wonderful world of stationary and craft products SO I’m just going to review this bottle of ink as it is!

As I said in my Diamine Imperial Purple ink review, Diamine is a UK based ink and stationary company that has been in business since 1864. With over 100 years of experience under their belt they are still coming out with great inks at ********great price**********!!

Diamine Oxblood is supposed to be a dark red ink and as you can see it definitely has a “blood” like property to it. Diamine Oxblood ink is one of the most popular inks in the Diamine line and if you scroll through the fountain pen subreddits you can see this ink often purchased along side demonstrator pens.

This ink write amazingly in my TWSBI Eco and dries quickly too. It is supposed to be a dark red but mine is more of a brown with hints of red in it … which makes me think that it might not even be Oxblood and that it could actually be Diamine Rustic Brown. I guess I’ll find out one day when I try out Rustic Brown, hah! ¬†Anyways, this ink is not really my style, I like more Red in my inks and less brown. I can absolutely see the appeal of this ink as it works well and looks cool too but I have never been much of a brown/earthy color person.
