## Overview

The Pilot 4 Colors Acroball Extra Fine Pen combines four vibrant, waterproof ink colors in one sleek, refillable ballpoint with a smooth 0.5mm tip. Featuring Pilot’s low-viscosity Acro ink for effortless glide and a unique tire-pattern rubber grip, this pen is engineered for professionals who demand precision, durability, and style in every stroke.

## Description

This pen is a four-color Black, Red, Blue and Green ballpoint pen that uses the Acro ink developed by the Pilot. The oil-based ink has 1/5 of the viscosity of conventional oil-based inks. The unique blend of ink and lubricants allows the ball at the tip of the pen to rotate smoothly by reducing friction. This creates an enjoyable, non-skip writing experience. The ink is satisfyingly pigmented and is also water-resistant. The pen has a unique rubber grip developed by Pilot that sports a tire pattern, which prevents your hand From slipping. The clip on the pen uses a coil spring with a "soft clip" Mechanism that can be clipped 100, 000 times without breaking, according to Pilot testing. Not only is it durable, The clip is extremely easy to open and use.

Review: Pen LOVERS - This is the ONE to own! - I'll just start by saying that I have autism and one of my biggest struggles is sensory issues with writing on paper. My top pens are the ones that glide across paper the way you could only dream of. I have tested nearly 900 different types/brands/styles of black ink pens and this pen right here has become my NUMBER ONE pen. PROS - SMOOTH WRITING: It writes so beautifully on all types of paper (my cheap Walmart notebook, my field notebooks, my expensive thick paper, napkins, etc). It's a fine tip WITHOUT being scratchy or damaging the paper (previously loved pilot 0.38 and 0.25 tips). - FINE TIPS: Pen is a 0.5 tip, which I consider thicker than what I normally love, but this writes and is thin like my 0.38 pen, so yeehaw for me. - 4 COLORS IN 1: I work in healthcare and round on so many patients, I hated carrying around 3 pen colors AND a highlighter in my fanny pack, so I started the hunt for a multi-color pen. My delight when I saw that Pilot made this one!! I've tried other competing brands / random other brands of multi-color click pens and they just don't perform as well as this one (they smudge, poor writing quality, weird weight). - SMALL: Its not overly thick/big with the multiple colors to ruin the ergonomic feel of it in your hand. My hand never gets tired. - REFILLABLE: There is only one other pen I have actually used so much it needed refilled on ink (which was the platinum preppy fountain pen), however, I have now worn TWO of these pens out in the black color. Luckily, refills are easy to buy so I can just swap out the ink since the pen barrel is so high quality and still looks brand new. CONS - The clicker's are placed at the TOP of the pen, so because of my small hands, I have to stop what I'm writing completely to reach up on the pen and click the colors. This is the one point that I do wish the clickers were in the same spot as this one cheaper brand on desertcart that comes in a multipack (they write well but they aren't as ergonomic/comfy in the hand). OVERALL This pen is my favorite thing ever.
Review: Great for nursing clinicals. - I love this pen for nursing clinicals! I had the classic four color but like this one so much more due to the fine point. The pink color is cute as well and I like the spring clip.

### ⭐⭐⭐⭐⭐ Great for nursing clinicals.

### ⭐⭐⭐⭐⭐ WAY better than Bic! Still too large diameter. I have only had a short time though...
*by J***2 on March 3, 2022*

I previously bought a 3-pack of BIC 4-Color Pro pens for about the same price as ONE of these pens. Around $7 for one of these, and around $7 for THREE of those. This is a better pen. The BIC is cheaper feeling (even though they're both plastic pens), the writing sometimes has little gaps and skips in it, and the clip is pretty useless (can't clip it on the color of a T-shirt or polo shirt and expect it to stay there, and it jabs you in the neck). I opened up this Pilot and it's a whole different experience. The writing is super smooth and skip-free, and the clip actually works. My only complaint is that it's like pulling teeth trying to find a narrow diameter 4-color pen, and this one is no more narrow than any of the others I have found. That stinks. And being plastic it isn't exactly professional looking or feeling. But whatever...it works well and does its job better than some cheaper alternatives. I will update my review after I have had it for a while and can speak to how it holds up with more use.
