-
Terrana phone cases are compostable and will naturally break down in soil after approximately 6 months, depending on environmental conditions.
This means your case will safely return to the earth, leaving no harmful waste behind once its life cycle is complete.
-

Funnily enough - we have been asked this question many times!
