Lots of fans of the Pyrex d/ts begged John at Theecig. to make them. Because the i06 is such a win, he did.Got my green one today. I have used the 306 ones so it doesn't really seem much wider to me. It is exponentially better than the plastic one thoughI do like how it is shorter than my 306 one was too. Was this something that was a collaboration and we will be seeing it on the IKV site or did they just decide to make these tips?
