Nano Pen

Love it!

It’s my favorite pen to carry on me all the time! Magnets strong and pen feels nice and hefty (despite its tiny size.) refills are available and I have no issues with how it writes. That being said, I’d change a few things:
The magnet in the cap. Altho strong, it can eventually stick to the pen tip coming out of the cap (I glued mine back in and it’s been working a long time)
Also, it would be nice if the back of the pen were magnetic as well so you can keep the cap parked there when in use.

The refill. I like how refills are avail, but there is no tapering on the refill & the hole in the tip of the pen is the whole diameter of the refill. It’ll never happen, but hypothetically the refill can come entirely out of the front.

All that being said, I love it. Thanks

Smart key

I love this KeySmart if you leave your keys somewhere your cell phone will alert you to find your keys


Always have a pen on me it’s great

Great little pen

I was surprised how heavy this little pen is. It writes beautifully. The cap stays on great due to the magnet. The only thing I don't like is when uncapped, the lid doesn't stay on the end; I have to hold it so I don't lose it.
