Works great, just like any other pen

Works pretty much exactly how I expected it to. I could see this being useful in emergency situations where you don't have a pen or pencil on hand to write down notes. I'm mainly using it for informal notes when I'm out and about. Tiny enough to just keep on your keychain and just forget about until you need it.

You might want more than one

I bought this as a gift for my husband and ended up taking it. I don’t usually carry anything to write with, but the pen writes really well and doesn’t fade or rub out. Highly recommend as the only tool on your keys!

This is a MUST for anyone in the office

The amount of times this has saved me, I'm starting to lose count. It's always there because you always have your keys on you.

The level of detail is really cool

Incredibly light weight last resort pen(cil) for my keychain. You can get a pen that weighs this little but you have to deal with ink drying out. This seems much more like something I can forget about until I think “oh ****, I wish I had a writing tool.” Also, appreciate no lead in the alloy.

Don't worry about a pen again

After losing so many nice pens over the years, this is finally one you can't lose. I always forget to take a pen out on jobs, but now I have my foreverpen on my keys. It's saved me loads of times!

Love the ForeverPen and the Pro, just wish I got another for my office

The Pro stand is ridiculously overbuilt; I love it!

Thanks WorldTiniest

Just received my two pens, one small, one regular size. And the work! It works on different paper structures and that's what I was looking for. Thank you!

The last pen you'll need
