I know most of you that read reviews and want to do your research before plunking down your hard-earned on a luxury ink will be looking at tons of other reviews of Edelstein on Fountain Pen Network and other pen blogs, so I'll make mine short and sweet.
Written review done on a Rhodia staplebound notebook with 80g paper with a Pelikan m215 fine point fountain pen. The Topaz color is rather unexpected up against the Sapphire. Smooth, soft in color, "Edelstein" is fun to say, nice shading, on the wetter side, bottle is gorgeous. Buy Edelstein Topaz at Goldspot and I will love you.
