Kim Nova fountain pen. The barrel does not have threads. The cap slips on. Made of ebonite, so the 'slip on' isn't as good as with regular plastic barrel pens. I didn't think that a thread less barrel would make any difference, but I must say, it has a really good feel. The nib was modified as per my request by the ebay seller (krishnapens). Broad, wet and buttery smooth http://i1262.photobucket.com/albums/ii616/rakshitpai/20140426_122558.jpg http://i1262.photobucket.com/albums/ii616/rakshitpai/20140426_122747.jpg
