The product is a vintage Pelikan 4001 Black Fountain Pen inkwell, with a capacity of 50ml. The ink color is black, and the brand is Pelikan. This fountain pen inkwell is a collector's item for those who appreciate high-quality writing instruments. Made with durable materials, this inkwell is perfect for those who enjoy using a classic fountain pen for writing or drawing. I am assuming that this is black ink I have not been able to open it to check, but I do believe it is black.
