I agree with Rick about woodnwhimsies being your best bet for replacement parts for a standard cigar . I just bought a load of the standard cigar clips in several platings , I like the simple design and the overall strength and flexibility of them and use them allot on my custom work , but since you are looking for the FANCY ultra cigar clip , like I said the person you get your kits from will be your best bet .
As for the nibs the cigar kits only come in one style , with the groves and bands , that is a design feature of the cigar kit , no one makes a cigar kit without those features . If you want a different look , try what Eric did in the challenge thread . I like the look of that and will by trying a few that way myself .
