The hypoallergenic glass is nonporous and body safe, and when cared for properly, is designed to last a lifetime.
Run the wand under warm water or place it in the microwave to heat things up. Chill it under cold water or put it in the freezer for a cool sensation.
Since glass is nonporous, cleanup is a snap. Use Toy Cleaner and warm water, or throw it in the dishwasher for a worry-free wash after the fun.
