I would have emailed this privately but have no idea how to do that. I have no clue where to get the crystals but would love to know where to get the neck cooler. How cold does it get? I am currently awaiting my third neck surgery (second one in the past year.) Cold works much better than heat to help decrease the pain. A cold collar would be wonderful at work I know this is off topic so you can email me privately at
