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

Danielle Rowley

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.

Jasmine Hambley

Beautiful case, really happy with it. Arrived promptly and well packaged. Thank you :)

Elizabeth Webley

I love my phone case. It fits perfectly, feels and looks great!!
Would highly recommend

Amy

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

Several purchases in and wouldn’t buy a case from anywhere else. Love the eco case, hard wearing, colourful and not adding plastic to landfill all great!!!

Jane Jones

This is my second case I've purchased from this business. I love that they're compostable and the designs are really pretty.

Anna Martin

Love my case! Really good quality and the colours are stunning, just as vibrant as the image!

Hannah Jelliman

Great item, have bought one before and was so good I got another for my new phone

Claire Rookes

Beauitful phone case, I ordered the wrong size and the store was very helpful when I asked if I could exchange it for the right size.

Maureen Higgins

Beautiful phone case, feels so much nicer than a plastic one

Izzy Romilly

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.

Robin Staub

Brilliant item, really lovely design and been using it a few weeks now and the picture hasn't scratched or faded at all. Very happy, great quality

Rosie
