25mm grip assist ring

this was a simple solution to fix a problem I was having with some of my rdta, rta, rda and the like where on some of them the ring on the bottom of the tank or cap is small enough that you can't really get a good grip on them which would often lead to unscrewing the tank parts instead of unscrewing the tank/rda from the mod this ring gave me enough of a surface area to be able to grip onto that it was able to solve my problem so I figured that I would share it just in case others might have a similar problem this was made for a 25mm tank with not much flex so if you have a bubble glass or even just like 5ish or so mm size difference then it probably will not fit good luck and i hope this helps
