Robert Oster was inspired by the dramatic landscapes in South Australia when he developed the Signature ink range and Deep Sea is no exception. Deep Sea is a well saturated greenish teal that was inspired by the beauty of South Australian coastline.
All Robert Oster inks are handmade and are non-toxic and come in recycled plastic bottles which are perfect for travelling. Ideal for writing and calligraphy with a palette of vibrant and intense colours. The long narrow ink bottle design also allows for easy refilling of your fountain pen.
