Hi Ron... So I'm thinking, 3 different pens?
Boy are those bad stinkers... better not to show... Maybe send them to me!!!
OK... The first looks like Blue Abalone??? VERY Beautiful!
The second. a Blue PR or Alumilite??? (I'll guess Alumilite?). Great color mix
Finally... a dusky Grey/white PR or Alumilite! The grey swirls are... very nice!
Great Trio!
Best Regards, Mark
