Smooth and lovely! Resists alcohol ink perfectly! It only needs a few seconds to dry and it can be immediately colored over with copic, Ohuhu, or any other alcohol based marker. No skipping, smooth even lines and quick dry time (5 minutes max and erasing doesn’t even smudge it). It does not hold up to water based marker Like Tombow brush, or water color (get a pilot multi ball for that) but if you’re looking for a fine liner that doesn’t budge with your copics, this is it!

I LOVE this pen. I thought I found my Holy Grail pen with the uniball Jetstream .7 (which is still a close second place now), but when I tried this one I was seriously blown away at the comfort, the weight and the quality of the gel ink. It writes so smoothly with no effort, no skipping and no smudging.
I was concerned that the grip would get easily dirty because it is white but it has remained clean and without any stains even after near constant use at work where I handle money a lot. I love the color of the embellishments. Highly recommend this pen!

In brief: Smooth, comfortable, very black ink.

In depth: I ordered the Clena as part of a large order of a bunch of different pens, as I wasn't sure what I liked. The Pentel EnerGel is a very popular gel pen, so even though I personally wasn't too excited about it, I ordered it. I chose the Classical Pink Clena body because, well, pink, but after I placed the order, I was filled with regret about the body because it looked so, so thick in the picture, and I personally don't enjoy the feeling of super thick pen bodies.

Well, I was very, very wrong, because of the 13 pens I ordered, the Clena has, by far, the most comfortable body. The grip isn't squishy, just a thin layer of silicone or rubber over plastic, but the whole pen feels just so, so good in my hand. It's light, so it doesn't have that luxurious, heavy feel you get with more expensive pens, but there's something about the design of the body and the grip that, again, feels so good. I love using it so much that I will create reasons to write with it.

The ink was also a pleasant surprise. Because the EnerGel uses a needle point, I expected this pen to write fine, light lines, but goodness, the ink is so dark, it rivals the Zebra Sarasa R (also in 0.5mm). While the Sarasa R has a blue hue to its black ink, the EnerGel has a more neutral tone. The tip glides across paper smoothly --- probably the smoothest of all the pens I bought --- with zero skipping. I haven't noticed much if any feathering, but it is noticeably broader than my other 0.5mm pens. Given how dark the ink is and how smooth it writes, I wish I had gotten it in a finer size, such as the 0.4mm, but I really have no regrets at all, and this was the pen I was the most unsure about.

Also, I would say that the photos of the pen on JetPens are bit misleading in regards to the color of the pen's body: in reality the pink stripes at the top are lighter, unquestionably "pink" rather than "light red" as the pictures make it appear. Very much a warm, midtone pink, while the body itself is a soft ivory color rather than a stark white (which I think suits the overall aesthetic very well). I personally wish Pental hadn't chosen brown as the accent color, but it's fine. It's a soft, desaturated light brown, with a cool undertone and used sparingly. The metal of the clip is somewhat interesting, as it seems to have an extremely subtle pink sheen to it, which is also seen on the button(?) to retract the pen.

A pure delight, this pen, and I plan to order another in 0.4mm, as well as plenty of refills. I will continue using this pen a lot.

This is the best gel pen ever! The body is cute and classy and... do I have to say more about the Pentel Energel ink? It's the smoothest and fastest drying gel pen out there.

An adorable pink body to match my pink stationary collection, and it WORKS WITH MILDLINERS. The ink is dry in moments and stands up to highlighting like a champ. I'm a happy leftie!
