I attended the Art Expo in Pasadena, Califronia, this afternoon, expressly to find a fountain pen that would be refillable, resist drying out or clogging when I sketch out in nature and was reasonably priced. Well, I found it is a Lamy with a refill adapter and it’s wonderful. The nib is not too thick, soft and flowing on any paper and the ink is water proof so I can watercolor wash over it.
The ink is India Black with No-Shellac so it won't clog the pen.
I was also able to replenish my palette and got some disposable drawing pens. I am posting the test results of the colors and disposable pens. I should be good for awhile.
I also found a small flat brush for my paint box. Very cute!!!
