Succulent terrarium, brass trim. 4.5” x 4.5” base, standing 9” tall. The biochar is the “dirt”. 100 g biochar provided which is perfect for small bathroom or foyer. The biochar lasts around 2 years, no need to "recharge" charcoal by taking it outside every month.
Biochar will purify air around you, getting rid of odors, moisture, mold, mildew, indoor allergens.
Note: Biochar does not magically erase the mold or mildew but it will stop it from growing. If you have mold or mildew growing in your house, get rid of them first by wiping the surface with vinegar.
