Using your Pipedream Icicles No. 78 Glass Massager is easy. First, decide if you want a warm or cool sensation. To warm it up, run it under warm water or place it in the microwave for a short time. For a cool feeling, put it under cold water or in the freezer for a bit. When using it, just enjoy the smooth and unique shape. After use, clean it with Pipedream Toy Cleaner and warm water. You can also put it in the dishwasher for a hassle - free clean. Make sure to handle it carefully as it's glass. Don't drop it or expose it to extreme temperatures suddenly. If you take good care of it, this massager will last you a long time.
