Really lovely case that feels nice to hold and sturdy enough to protect my phone

Danielle Rowley
Turtles Eco-Friendly Phone Case

Love it! We usually buy from Pela but they're so expensive & take forever to come. So happy to find another provider of compostable phone cases.

Would highly recommend

Amy
Turtles Eco-Friendly Phone Case

This is the second case I have gotten. I got my first case in March24 and it started to decompose Aug25. Honestly I’m really happy with that! I love that my phone cases DO NOT last forever and will biodegrade. I also like how the case feels- I got the mate version and love it. I plan on repurchasing in the future.

Estefania

Love Spell Eco-Friendly Phone Case

I wanted a nice looking, biodegradable case. This case looks exactly as pictured. It fit the phone perfectly and it has a nice grippy texture to hopefully prevent drops. I can press the buttons through the case without much effort. The inside corners are scooped out a little giving some room to give on impact without breaking the phone or case - nice quality detail. The ink of the turtles and logo shimmer a little in the light. Overall, it actually exceeds my expectations.
