### ⭐⭐⭐⭐⭐ Great, smooth writing.

I specifically ordered these pens because they are green ink and don't require caps to close as they retract. I like them but wish the ink was a darker green.

### ⭐⭐⭐⭐ Great pens but....
*by J***R on March 28, 2017*

Worked great roughly a week of constant 6 hrs of use (work), then the pens tend to bleed. A lot of ink still left in them for it to short out.
