I purchased this because my previous one (same model but pink color) broke. The old pen body cracked so every time I tried screwing the grip of the pen onto the body, it would just fall off. That one lasted me exactly 8 YEARS with constant usage and this specific model is still my favorite hence I ordered another one! I wanted this yellow one because the other color options available were kind of boring and typical.It's comfortable to write with the pen as it has a rubber grip. Each of the 4 ballpoints (black, blue, green and red) write very smoothly and the mechanical pencil works well. The 0.5mm ballpoint width is perfect as I write small although I think this style pen does come with 0.7mm or 0.38mm. There's even a small eraser at the top with a detachable cap which feels pretty secure because it clicks into place. With time though, it might become more loose because I recently lost the eraser cap to my pink one.Each of the ballpoints are replaceable which is great. Just make sure you order the correct refills. I am a healthcare worker and having the different pen color options and pencil is a must. Highly recommended 10/10!

This pen is how San Diego stays classy.†— Ron Burgundy, circa late 2010s penmanship con.Looks classy, feels classy (smooth, weighted hand-feel), classy materials (I’m a sucker for the shiny enamel-looking barrel, and the nice grip), writes classy (function perfection!). Quick and easy bounce-back between colors and pencil lead, when you want to change how you’re sketching schematics in your captain’s log.This pen IS class.

One of the best multi pens I’ve ever had. Writes unbelievably smooth! Enjoy the functionality, style, and craftsmanship….the yellow color is a plus!

Super comfortable to hold, writes smoothly and dries right away. Nicest looking one too.

I wrote a detailed review for the second one of these I bought (in purple.) To make a long story short: I love this no-smudge-ink pen and pencil device. It's the one I keep in my purse, and my plan is to buy more for gifts.

Once you start using this pen, you don’t want to go back to use other pens anymore. It’s very smooth.

Ordered three of these and two of them arrived with the black ink already dried out. Will not buy again
