K132. Bister Ink Complete Kit.
This kit contains all you need to mix up your own Bister Inks. Kit includes 1 of each Bister Ink color, a copy of Amity Parks' article "Bister Ink" from Bound & Lettered 16.1, two Jumbo Dinky Dips, and a Mini-Spoon Set.
I believe every calligrapher like using walnut ink crystals because we love the gradient effect, Bister ink set provide different colour like this, especially when I mix with those 8 colour on my letter script. 1oz powder can mix over 4oz ink that it is well worth it. From now on, I will use this instead!
