.....a new ivory substitute? I have been searching for a material that would be a great ivory substitute and finally found one. This material machines and works nicely. It is slightly yellow, more just off-white. With time and handling it will take a patina just like real ivory does. But, and its a big BUT, can I successfully market it? The price is quite high. A 1 1/2"X1 1/8"X5" piece would be $25.00. Small good news, with the purchase of two or more, I would cover shipping. This size is, of course, adequate for the largest pens, like Emperors. Before I make the investment, wadda ya think?
