Pilot, Precise V5 RT Refillable & Retractable Rolling Ball Pens, Extra Fine Point 0.5 mm, Assorted Colors, Pack of 12.

[This review was collected as part of a promotion.] I received this product from Influenster to try and review. It came with a variety of colors. They write smooth and don't smudge. I like the fact that they don't stop writing like regular ink pens. The gel is consistent and smooth. The colors are vibrant. I would definitely buy these. I wrote with the black one at work all day today.

[This review was collected as part of a promotion.] This pack of pens is so fun because you get 8 pens in every color of the rainbow plus black, all in extra fine 0.5mm tip rolling ball pens. When you write or draw with them, the ink is so smooth and the color is pigmented. Writing a note or shading a drawing, you're not gonna get any skipping, and the color is vibrant. Conveniently, these are refillable, making them last longer and even bringing down the cost of replacement without having to always buy new pens (and use less plastic that way). These are so smooth, reliable, and the colors make them a lot of fun.
