Our biodegradable plastic is not hard but also not as soft as silicone. This means that the case sits extremely securely on your smartphone and can withstand external conditions very well. Since we do not use coatings, otherwise the case cannot degrade, you should be a little more careful with sharp objects, as scratches could otherwise occur.
Our cases made of apple leather, on the other hand, are not biodegradable but 100% recyclable. They offer the same comprehensive protection and the same stability. However, the apple leather is much more resistant to scratches, oils and dust.
In the end, it depends on your usage conditions but both cases promise longevity.
