I’ve been getting mine from Paper Source – http://www.paper-source.com/cgi-bin/paper/color/Eyelets/2904.012/702.html.I don’t know about tightness – I hammer mine down tight for book binding purposes, and don’t want anything turning, but they seem high enough to stay loose for turning paper.But they don’t have brass, which I’m also looking for. I thought “Metallic Gold” would be close, but it’s a painted dark yellow, and not very metallic. Anyone else have a source for brass?
