That really does happen too!
Now that really is a neat idea. For those who stealth vape at work at their desk, there would be no reason to hide it between vapes, just lay it down on your desk.I was sitting at my desk writing notes with a "Pilot Precise V7 Fine Ballpoint" pen, then I took my 510 out of the walgreen's hand sanitizer case in my pocket for a quick stealth vape. My pen ran out of ink at the very moment before I put the 510 to my mouth. I happened to notice that the diameter of the pen and the diameter of the 510 are pretty similar. I took the cap from the pen and put it over the LED. BAM! It looked like I was chewing on the end of a pen. It holds the end of the battery reasonably firmly and covers the LED for stealth vaping quite well. I thought this belonged with your bic pen mod. Great work, btw.

I like the idea of different colors too. I keep my atty's with specific flavor carts together and with different colors I can quickly identify the different flavors at a glance.Great idea. I now have 3 in clear, blue and red. Makes it easy to track which battery was used last and where you are in the rotation of your batteries.
GL and Happy Vaping
