This 50ml ink is non-toxic and comes in recyclable PET plastic bottles that are produced through totally carbon neutral processes in Australia. They are slender to store and you won't have to worry about breakage.
Robert Oster Signature Inks prides itself on its unique colours that are a genuine inventory of the Australian palette. Oster became interested in fountain pens in 1989, and from there he developed a desire to produce inks that reflect the rich culture and colours of the wine region of Coonawarra, South Australia.
