It's back-to-school season! Admittedly, the majority of the stationery supplies I have to acquire for my children at this time of year are not as exciting as the stationery I'd like to be playing with, but ALL stationery is fun in its own way. I wish I could send my kids to school with a box of Blackwing pencils, but it will have to be the store-brand #2 classics, as requested by The List.

But pens? We can have a little fun there. Gel pens are a staple of note taking in school, but The List doesn't say what kind they have to be. We have our old reliables, but it's always fun to try something new.

Pentel EnerGel Kuro

Pentel has a new build of their EnerGel model called the Kuro, and I think it's the perfect gel pen for this year's school adventures.

The Kuro has a slim body in a black rubberized material that is all non-slip and slightly cushioned, and the grip area has extra texture to it. It's smooth, but textured enough that your fingers don't slip on the barrel. It has a lightly flexible plastic clip and a click button top. The clip and click are in the color of the pen's ink, for easy identification.

Pentel EnerGel Kuro Tip

The tip is 0.7 mm, and it writes very smoothly. It downright glides. I had no skipping or blobbing with these, and I've been using them all day every day at work for a week.

Pentel EnerGel Kuro Ink

The ink is nicely saturated with bold, bright colors available in the set. This set has black, purple, pink, red, blue, light blue, green, and orange--enough colors for some excellent color coding. There are also 12- and 24-color sets available, as well as individual pens. They've been great in my planners, especially because they have a quick-dry, no-smear ink. They are also refillable. The nose cone unscrews to access the Pentel LR7 refill.

Pentel EnerGel Kuro Refill

The 8-color set costs $13.50, with individual pens costing around $2, and refills cost $1.35. Overall, they're one of the more affordable gel pens out there right now, which makes them even better for school, where pens vanish into the portal that lurks at the bottom of every backpack.

I've really enjoyed writing with these pens. And while I've turned the standard colors over to my children for school, the pink, purple, and light blue have stayed on my desk at work. Because mom has homework, too, and everyone needs good gel pens.
