Hi,
I don't know if you sell any of your pens, Oldtimer, but if you do then acrylics will increase your earnings. Most of these will be bought by men for women, or by women for other women. And remember, it ain't only pens. Just take a look at George Watkins' beautiful boxes and jars in acrylic - they will break your heart (someone on here will know George's website, I'm sure.
Bob.
