Stylish, fit in Hand excellent and my wife keeps stealing the pan because it fits in her hand properly

Great pen for wallet as backup

If you want the most absolutely thinnest pen thats still clicky this is it. Hand will cramp trying to write anything more than a few sentences for it's fine for a quick note.

The THINNEST pen on Amazon. It is just 3.5 mm thick which is just over 1/2 as thick as the second thinnest pen. This is great if you want bragging rights, but if you actually have to write with it, not so good. I don't have large hands, and I can barely hold it and as such, it changes my handwriting. Your signature may not be recognizable.The mechanism to extend and retract the tip works fine - they have descriptive photos in the item description. It is not only thin, but it is only about 3.5 inches long. The short length also accounts for some of difficulty holding the pen.One surprising detail is that the ball point is a fine tip, but it draws a pretty dark, bold line, and it writes pretty smoothly. I also suspect that it is nearly impossible to find replacement ink cartridges for it, so you'll probably have to buy a new pen when it runs dry. Given the short length and narrowness of the cartridge, I'd bet it runs out in less than half the time of a normal pen.Overall, if you are looking for the absolutely thinnest, smallest pen you can find, this is it. But if you have to actually write with it, you may want to keep looking.

It's tiny, it fits in any wallet it's perfect for people that does not like bulky pockets

Got this pen for my grown son. He loved it. He's a collection and gadget guy.It's the neatest thing. I'm ordering refills for it.It's really not too hard to hold. It's for jotting and signing... not writing papers or manuscripts... be fair. It's a great conversation starter... say nothing... just use it... someone will start talking to you.I live on little means - di$ability - and I looked and looked for a nice gift that I could afford and saw this pen... it's so affordable that I got one for myself, too.It's durable for It's purpose but I can guarantee you'll be looking for excuses and ways to use it... I sure am!! It's so CUTE AND USEFUL! I keep mine on a necklace. Not heavy, not banging on things when I bend. It's fine but strong for its tiny mighty size (BARELY over 3 inches).Get yourself one... get one for someone else, too!

This pen looks alot bigger on the picture. ALOT

While I was hoping the pen would be very thin, it is also extremely short. I was disappointed when I saw the size of the pen. It could benefit from at least another half inch in length
