Olight O’Pen 3: The Best 4-in-1 Pen You’ll Want to Steal
Hello, my name is Connie, and I am the reason pens have chains on them in various businesses.
I am the sole reason that when that sweet receptionist hands you a pen, there is a massive plastic sunflower taped to the top. (Pffft… little do they know, I’m actually a huge Sunflower fan too!) I am guilty of getting home with a new pen in my purse more times than I care to admit.
Yup. I have a full-blown pen addiction.
And let me tell you, my Olight O’Pen 3 is going to need a HUGE sunflower AND a heavy-duty chain. (That is, if I ever actually let anyone borrow it in the first place!) Somebody find me some duct tape and a plastic flower immediately, because this pen is 100% steal-able.
Why the Olight O’Pen 3 is the Ultimate EDC Pen

I’ve owned a lot of pens (mine and other people’s!), but the Olight O’Pen 3 is in a league of its own. It’s not just a writing instrument—it’s a complete 4-in-1 everyday carry (EDC) multi-tool.
Here’s why this sleek little gadget completely blew me away:
- 4-in-1 Versatility: It packs a bright 120-lumen white light, a soft LED pen-tip light for nighttime writing, a red beam for preserving night vision, and a green beam for presentations or pointing things out across the room.
- Safe Green Beam: Don’t worry about safety—the green beam output is ≤ 5 mW; (Class 3R), meaning it’s completely safe for human and animal eyes during everyday use. HELLO! I have to wear out Walter before bed. Attacking this green beam is SO FUN!!
- Hidden USB-C Charging: No hunting down weird button batteries! The built-in rechargeable battery charges fully in about an hour through a slick, hidden USB-C port, giving you up to 25 hours of runtime.
- Bolt-Action Switch: The upgraded 3-position bolt-action mechanism gives you smooth, tactile, one-handed control over your lighting modes. It’s unbelievably satisfying to click!
- Lightweight & Ergonomic: Crafted from durable aluminum alloy in a gorgeous army green, (along with pink! 2 best colors EVER!!) it weighs only 33.5g. The meteor-shower-textured grip feels amazing during long writing sessions, and the sturdy pocket clip keeps it secured to your planner or notebook.
Whether you’re taking notes at work, navigating in the dark, or running through slides during a big meeting, playing with dogs or cats, the Olight O’Pen 3 balances utility, style, and effortless function. (and FUN!! I really don’t think you understand the fun part of this pen! So, let’s add a video!)
Did I mention OLIGHT includes an extra ink cartridge? Yup, it does. AND an extra-long 32″ usb c to c cord.
