Ooo, either Black Python in Pearls and fill it with Sailor Jentle Black or Ghostly Lapis and fill it with Akkerman's Shocking Blue.
In fact why don't you buy both as YOU WILL buy another in the future and this way you'll save on postage
I love my Konrad. Beginning to wish I wasn't an early adopter. Mine's red swirls on the body but plain red caps
The nib & flow is fantastic though . . .
I bought mine and some ink from Pure Pens and they were wonderful to deal with.
Best of luck.
Photos of your choice soon please . . .
(I'd recommend Noodler's inks but don't own any that would match the new funky pens)
