Until the Luxury Brands Ink Miser Inkwell gets off the ground, we have the Erka Inkwell available from Goldspot Pens for about $ 15 for three, so around $ 5 each. I have six and find them most useful. They are listed under Rohrer und Klingner inks. Fit the R & K bottles, Aurora bottles, and others too numerous to mention.
The thread on the Erka is amusing and goes on to quite a length. Recommend looking it up when you have a few minutes.
Really enjoyed the comment that the Ink Miser is the only inkwell insert that "exactly fits" the Noodler's three-ounce bottle. The Erka is a bit smaller and does have some wiggle room. If you aren't careful, it may come out with the cap when you open the bottle.
From a person's actions, we may infer attitudes, beliefs, --- and values. We do not know these characteristics outright. The human dichotomies of trust and distrust, honor and duplicity, love and hate --- all depend on internal states we cannot directly experience. Isn't this what adds zest to our life?
