When we think about crossing, we envision adaptability, sleek design, and excellent quality. With the 510 extension, such thoughts appear to be back on track. Fit one end of the 510 Extension to your favorite Box Mod or 510 threaded rig, then connect the other end to any 510 thread atomizer. And just like that, you have a portable E-Rig at your disposal. We extend an opportunity to take your sessions to the next level.
