Review (4/5): Useful storage case if you plan to chill before use
I purchased this model because it came with silicone storage case for keeping in the frig. Use to “roll-in” serums before applying moisturizer. If you use as directed the quartz roller is warmed by the skin before finishing. Better to roll as directed once, starting with neck and then face. Then go back and do full massage of neck/face after quartz reaches skin temperature.
