Far, far too many devices for scribbling.
They look great - especially when used with a flourish and for illustration as you have done here. What's the one that you wrote the intro to the post in? Do they all show the silver if you are just writing normal day to day stuff, Scribble?
The intro was written with Heliogen Green - and yes, the sparkle does seem to show up well even in normal use : )
All comments are moderated - but I'll try to get them up on the site as fast as possible!
