Olight O-Pen 3 Penlight

$79.99

The Olight O-Pen 3 is a bolt-action pen and a penlight in one, and it comes apart into two functionally independent pieces so you can carry just the light if that is all you need.

The light is built into the pocket clip: a 120-lumen white beam with four output levels, a two-stage red light for night vision, and a red SOS mode. A soft tip light lets you write in the dark. There is also a Class 3R green laser pointer with two brightness levels. Every control sits on the bolt, which keeps the body clean.

The shell is aluminium with a PC lens, and the hidden USB-C port takes it to full charge in about an hour. When the ink runs out the O-Gel refill drops straight in.

Not only is this a 5 star review, I am going to throw 5 more ⭐️⭐️⭐️⭐️⭐️ making it a 10 star review ! Scott is such a nice guy. In this show I bought flashlight and then at the end of the show I got picked for the buyers givvy at the end of the show. Scott knew that I really wanted the full size pen made by Olight and he gave me the option to upgrade ( for free ) the prize. He told me to pick a hand and I picked his left and wow it was the one that I wanted and the other hand was a knife with a leather sheath. Now I don’t know if the pen was in his left hand under the table or if he switched it to his left hand because he knew that was what I truly wanted. Regardless I ended up getting what I was wanting so THANK YOU Scott you are awesome !!! During the same show he ordered a knife that he didn’t have that I wanted because it would save me some money if he purchased it instead of me just spending more buying it from the manufacture. Now all I have to do is hope that no one runs me up.

The knives I bought are Extremely nice and the prices of them were Great - The O Clip light is very nice and bright for its size - The mini pen and pencil is smaller than it looks. I have very big hands so I will probably end up giving it to my wife. - The O light i3T - 2 Is a nice color but it is extremely dim for the advances in flashlight technology that other light makers are utilizing. I have a Nebo flashlight about the same size that puts out 3 times the light that the i3T-2 does. - Overall not a bad deal. - Shipping went out same day or early next day - Package arrival time from purchase was remarkable - Thank You
