16mm coil or 20mm coil?

[NimbusVapor]

Please help!

I am trying to order one of the enail bangers from a website but I am unsure if my coil is 16mm or 20mm and I dont have anything to measure it with.

Does anyone have any idea how to tell them apart without measuring?

quartz banger ? if its a thicker/larger bowl then its definitely going to be a 20mm regular coil

The thick banger i got from my local smoke shop about a year ago definitely doesn't fit my 16mm regular coil. haven't tried the 20mm
