Warm and confortable, this collar is very simple to use:
open the sealed bag, extract the heat pad and shake it for a few seconds.
On contact with the air the pad is activated and generates heat for over seven hours.
Insert the heat pad into the pocket and apply Necky around the neck.
The pad is single use, but you can stop the heating process by putting the pad back into the plastic pouch and squeezing out as much air as possible before closing it.
You can use it again at your convenience up to a total usage of seven hours. When you need to use it again, take the heat pad out of the plastic bag, shake it for a few seconds and put it in the external pocket of Necky.
For increased comfort you can adapt its shape to fit your neck size.
