Zonon 4 Pieces 6 in 1 Multitool Tech Tool Pen Key Ring Screwdriver Pen with Ruler, Two-head Ballpoint Refills Metal Tool for Office Staff, Construction Workers, Red, Yellow, Blue, Black

I love these pens because, well...you never know when you'll have to sit down and write a novel, or measure stuff, or replace a watch battery, or tighten a screw in your glasses. Also, if you have large, thick fingers, typing on the tiny keypad of a smartphone can get ugly unless a stylus is available. Just one drawback, however; placing it on a keyring will damage the markings on the measuring scale, and these sorts of pens tend to unscrew themselves as you walk, so you migh find it has gone missing even if it was never loaned to a penless person.

tool is very handy but dont use 4 inch ruler to measure accurately. one inch is actually 2.5 inches. it seems i am frequently measuring things and it is still useable as long as you realize the error. it took some doing to pull screwdriver out to switch to flat head but once it did it is easy to switch. i use phillips end to tighten screw on reading glasses perfect fit.

These are awesome honestly! I’ve bought many variations of something like this and they all break or pop off in your pocket/purse. These are very sturdy and I absolutely love that the stylus is covered with a twist cap because that prevents it from popping off accidentally. Love these!

Garbage. Do not buy. I bought two sets at different times, thinking I got a bum batch first time. Wrong. 1. Pen falls off the attached ring. It just breaks away. 2. Tip loosens on its end. 3. Ink can be spotty. 4. Stylus doesn’t work. Waste of money! Great concept. Just what I needed…if it worked. It’s a fail at every element of the pen. The only part that works is the key ring itself. Will not buy again.

These are nice, solid small pens that have a 4" ruler on the side, a stylus hidden in the cap, and under the stylus is a mini screwdriver that is supposed to come out and flip over from a phillips head to a flat head. Unfortunately, none of these actually come out without pliers so that is a feature that isn't very useful. The stylus does work as expected. My only other complaint is that one of the pens came with an empty ink cartridge that also didn't have a ball point so it can't be used. Even with these few complaints, we do like these pens.
