One of the most fun uses of the wand is soft and sensuous. This massaging roller allows you to roll on the skin while it provides a soft champagne-bubble fizzing. Relaxing and pleasant, and a perfect way to warm up. Two vacuum chambers are filled with blue gas and red gas for a great two-tone effect. The mildest glass electrode available, it is a good way to introduce someone to violet wands. Rolling head rolls freely, held by a clear acrylic, pivoting support for optimum motion. Sparks as it rolls.
