THE CASE
THAT CLEANS
ITSELF
Felted wool infused with natural soap berry compounds. Inspired by hippopotamus skin's protective oils. Slide in dirty, pull out clean.
✨ The Wow Moment
You drop your phone in a muddy puddle at a festival. Panic. You pull it out, coated in mud. But you slide it into your HippoCase—and somehow, the wool wipes the screen clean as it enters. Later at home, you realize the case absorbed all the mud. Your phone is spotless, and the dirty wool at the bottom of the case shows you exactly where it captured the mess.
