For most part all stammers will snap just by applying a bit of pressure either side while holding in your hands. Just like snapping a chocolate bar just thicker.
However, from time to time some tablets are more stubborn than others. In that case I like to get a rolling pin or a hammer out.
Wrap the naked steamer in a towel and give it a wack, then wrap the broken pieces back in the bag to keep them fresh.
Keep wrapped in a dry, dark place away from UV lights and humidity before use. Essential Oils can be affected by the sunlight or evaporate if not properly stored.
For best aromatherapy experience Use within 3 months from purchase.
