Smooth cow bone with a metal nib, each one has a unique color to it. The nib is replaceable so the pen can be used for years to come. They will fit in all of the writing boxes.
6" long
A really unique (to me) writing tool. Well made and nice looking. The nib is pretty still and sharp so don't expect to do any fancy calligraphy. I'm having enough trouble relearning my cursive. Also, for best results use paper with a high cotton content. Sadly, the pen broke while cleaning. Most likely due to rough handling and not to a defect. Luckily, I had the Horn pen as a backup. I did save the nib as it is interchangeable with the Horn's nib. I'll certainly replace the Bone pen on my next order.
I received my pen today and it is extremely well constructed and really nice to look at. It does have that vintage look and I can't wait to use it tonight. Highly recommend.
