## Description

desertcart.com : RANBOS 4-in-1 Four-Color Multifunctional Pen, Black/Red/Blue Ballpoint Pen and 0.7mm Mechanical Pencil, Metal Case Pen, Great Gift for Friends, Loved Ones (Gray) : Office Products

Review: Excellent Multifunction Pen for the Money - This multifunction pen is very inexpensive and my expectations were quite low. I have been pleasantly surprised. The barrell is metal and painted with a quality laquer paint. The four functions (black, blue, red, and 0.7 lead) are fully spelled out and easily readable at the top of the barrel. The mechanism to extend the ballpoints or pencil works smoothly and easily. The ballpoint refills write well -- no skipping and bright bold colors. The pencil seemed a little "loose" at first, but I have gotten used to that and I no longer notice. I use this primarily when reading books to underline and annotate. If that is what you are looking for, I am certain you will be delighted.
Review: Convenient sleek design - I like the sleek design that does not take up much space (say, in the pencil case or bag) and the comfortability is great despite it being slightly weighted. You need to get used to the functionality, though. Some dexterity and learning curve required. Value for money is good because it comes with replacement pens and eraser bits!!! It’s fun to see how such an un-bulky pen has four different colors. Slightly heavy but not bothersome. The pen writing gets a bit slightly stiff, and the ball diameter is thicker than I thought, so it’s not a pen that allows me to fast-write.

### ⭐⭐⭐⭐⭐ Convenient sleek design
*by L***W on January 14, 2026*

I like the sleek design that does not take up much space (say, in the pencil case or bag) and the comfortability is great despite it being slightly weighted. You need to get used to the functionality, though. Some dexterity and learning curve required. Value for money is good because it comes with replacement pens and eraser bits!!!

### ⭐⭐⭐⭐ Beautiful pen and excellent ink; eraser is hard to get at
*by M***T on September 20, 2025*

I was torn between four and five stars for this item, but I'm happy with it overall. I rely on a paper calendar and paper shopping lists, which I carry in my purse. It makes a big difference for me to have different colors of ink available, plus erasable options (whether that's erasable pens or pencils -- I enjoy both). I keep lots of separate pens/pencils/etc. at my desk, but I wanted something compact for my purse, and preferably something that was also attractive and refillable, which is why I bought this. Pros: * Comfortable to hold and write with * Easy to use once you've read the instructions, and it gives the right color consistently * The ink is shockingly good quality -- bold colors, fine point, smooth writing, doesn't require heavy pressure, and the ink doesn't smear * Comes with refills * Beautiful color Cons: * The cap for the eraser is difficult to remove, even after taking it on and off several times * The eraser doesn't erase quite as cleanly and easily as I expected * VERY tricky to remove and reinsert the ink cartridges Given how difficult the eraser is to access, I probably won't use it as much as I've done historically, which takes a little of the sting out of the eraser not being as nice as I wanted, but that's not much of a silver lining since the availability of an eraser was a major factor for my purchase. I haven't used up the ink yet to require replacing any of the cartridges, but I tested that the same day that I got the pen, and I honestly thought I'd broken the pen. It took me half a dozen tries to get the ink reinstalled correctly, and it doesn't let you select the different colors if it's not installed correctly. Once I figured it out it was fine, but I spent 20 minutes worried I'd broken it before I got it right. I haven't decided whether I'll order refills for this pen when I need them, or try another similar option. It'll probably depend on how long the ink lasts (if it goes a long time on top of being so excellent then it's a great value even with the tricky eraser) and whether the eraser cap gets easier to use over time. If the eraser remains difficult to access over time or the ink dries out quickly, then I'll likely switch to something else.
