While I enjoy vac pens, the way they almost seem half full bugged me. No any more. This gizmo instantly turned my see-thru pen into a dark red one. That's how full it was.
My shopping experience with your store was very enjoyable and I look forward to having future dealings with you.
I thought I was buying ink (silly me) Now I'm interested in vacuum fill pens, yet another thing I never knew existed!
