Coffee Monster - 50mL Robert Oster Ink
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...
Coffee Monster is a dark brown that looks like a cup of black coffee, and dries like a coffee stain. How fitting is the name for our store?
