Fits the Joyetech AIO - 19mm diameter version only as found here - LINK
These silicone skins are useful in a couple of ways
These skins are a tight snug fit - turn your AIO off (5 clicks within 2 seconds) before fitting as the button will be unintentionally depressed during the fitting process, as mentioned these are a tight snug fit - ensure the AIO button lines up with the silicone button.
NB: Failure to do so may lead to unintentional firing of the AIO.
The skin also has 2 cutouts for the tank and a cutout for the Micro USB port.
When installed, you may no longer be able to see the Max Fill Line - this is either where the AIO changes colour or as indicated by a line on the device.
Warranty: DOA only for manufacturing defects only.
