thanks for this.Best deal around in my opinion ... been using Thornton's Luxury since the start of the year and actually just recently restocked 2 more bottles. Not sure if it will work on your cheap copy paper but it fulfills my every writing need and I can trust it in my finest pens.

Sure is a bargain for a quality European ink. I've only used the blue.
I have no affiliation with this volume seller, just a satisfied customer.
I have 2 blue, red and purple bottles wending their way to me now.
