The fact that the autumn leaves are falling reminded me that I have Diamine Autumn Oak in my Lamy AL-Star Copper Orange FP and have not reviewed it yet. The pen has been filled for quite a while, so the ink may have darkened slightly but it's now a lovely autumnal colour. Not yellow, but a darkish orangey golden brown. It's truly an autumnal ink. I've written with it on different papers to show you the effect on a paper you might have. My Tomoe River notebook has heavier TR paper in it. I think it might be 68grams, but I'm not sure of that. These are photos not scans and have been corrected using Photoshop. This isn't sold as a waterproof ink,and shows no noticeable water resistance.It exhibited very good flow and lubrication and I found it particularly smooth to write with. I saw no skips or hard starts while I did swabs and dry time tests.It exhibited excellent shading.It is currently available in 80ml glass bottles or 30ml plastic bottlesDiamine sell it directly to end-users on their web-site.It's a reasonable price.
