I think they look great. I've used the purple blank on the left before and have always been happy with it's looks. I've also noticed that it seems the ladies prefer acrylic.
Bright and colourful acrylics probably sell about 12, to 1 wooden pen in my area , women especially always seem to go straight for the purple or red acrylics.
I am always a bit dissapointed when the wooden pens dont even get a second glance.
