Perfect! I've been looking for something small enough to slip into my jeans
pocket -- this is about 4.25" by 2.75". It holds my driver's license, debit
card, cash. I've also got some of those half-size index cards in there, with a
tiny pen (Zebra Mini T-3 Ballpoint) clipped under the flap -- this pen doesn't
protrude at all. I love this.
I couldn't find any reviews on this pen, but I bought it anyway just because
it's so beautiful. I'm very pleased with it. The cap slides snugly onto the back
end, making the pen full sized and well balanced. The ink is dark and it writes
very smoothly. This one's a keeper!
