Use a Shower Burst Sachet to get the most out of the Shower Burst tablet. For best use, unwrap one Shower Burst tablet and place it in the sachet. Hang and splash with water. When activated by water and humidity, the tablet releases essential oils for an aromatherapy experience. Re-wet the tablet in the sachet and use for multiple showers for the longest-lasting experience. The Shower Burst Sachet can be reused with any Shower Burst tablet.
