Today, I’m going to show you how to refill your GEEK BAR nicotine pens. It’s a great way to save money and reduce waste—no more tossing those empty devices! First up, grab a small flathead screwdriver or a razor blade. Carefully cut around the base of the mouthpiece to remove the paper wrap. You don’t need to push hard; just break that seal to reveal the snap-together parts hidden underneath. Next, take your channel lock pliers or the flathead screwdriver to gently pry off the mouthpiece. You've got to wiggle it a bit—just be careful, as too much force can damage the seal, which you definitely don’t want. Now we move on to the O-ring seal. It’s that rubber piece covering the juice holder inside the device. Take it out gently; this step is crucial for holding the liquid properly later on. Now comes the fun part—refilling! Pour your favorite e-liquid flavor into the juice holder. Make sure not to overfill it because you need a bit of space for the O-ring to ensure a good seal. Finally, put everything back together, charge it up, and you’re good to go! You can now enjoy your refilled GEEK BAR, so stop throwing them away and make the most of your vaping experience!
