Day To Night - 50ml Robert Oster Ink (exclusive)
One of the two bottles of fountain pen ink colours made just for TheCoffeeMonsterzCo! See it in action on Instagram and on Youtube.
Robert Oster Signature is an Australian ink company, famous in the fountain pen community for their quality inks. When I first started using fountain pens in highschool, I spent many hours browsing the range of Robert Oster colours, making a wishlist of inks I hope to purchase one day. It is surreal that in 2024, I got the opportunity to work on this project with Robert himself, and introduce these beautiful shades. Speaking of which...
Day To Night is a gorgeous plum-purple that represents the moment when the sun says goodbye and the moon says hello.

Beautiful color
The ink is beautiful and the stickers awesome as usual 😀
Beautiful ink!
I inked up my Pilot Elite E95s, extra fine gold nib with the Day to Night ink, and it’s amazing in my 2025 Hobonichi Cousin. It’s a gorgeous dusky plum color, does not feather, minimal shadowing except where I laid ink down heavily, and no bleed through. See pics. Look higher for the TWSBI Eco, fine nib with Private Reserve Tanzanite for a comparison example of notable bleed through. Highly recommend this ink for Tomoe River paper.
Such an interesting ink! Really dusky dark purple
