Robert Oster Signature Inks are made in Australia, inspired by Robert’s lifelong passion for colour and imagination — in his words, what “you see is what you get,” with a commitment to “under-promise and over-deliver.” They take sustainability seriously: their 50 ml bottles are made from recycled PET plastic, chosen because it’s among the most recycled plastics in the world. The inks themselves are non-toxic and eco-friendly, and Robert Oster maintains just-in-time production — bottles are often filled and shipped shortly before sale, minimizing waste. Beyond the product, the brand also gives back: 20% of pre-tax revenue supports global charitable causes, including women & children’s refuges, mental health, education, and food security. The result? A well-behaved, vibrantly coloured ink that feels like a thoughtful, ethical choice — truly “a drink for your pen.”
