The O-Ring replacement seal kit allows you to change your visible o-rings on your Subtank Mini to Blue, Black, White, Pink, or Red (Original Replacement). Within five minutes you can change your Subtank Mini's appearance to match your mod, vape pen, or mood.
There are no special instructions for the change, simply disassemble your Subtank and replace the seals one by one, then put it back together in a couple of minutes. There are five packages and each package contains 3 rings.
