I'm up and down ladders all day long. I'm working in the rain or snow or heat. I was always breaking pens and making a mess or sharpening a pencil every time I needed to write.Then came the Space Pen, the perfect pen, the only writing instrument I'll ever take on the job with me again.The size is perfect. Closed, it comfortably fits in my pocket and never jabs me, never breaks, never leaves a mess. I've been using my space pen for 3 years and it's not given me a bit of problem. It writes anywhere, anytime.Opened, the cap fits right on the back and it's a full-sized pen, writes well and looks good. I can hand it to a client and they always look like they want to keep it for themselves.
