About us

My name is John Griffin, the founder of Killer Koozys. I'm an American born and raised "guiri" living in Barcelona for a little over 5 years now. For as long as I can remember drinks were better when they were cold – and they were even cooler when they were served in a cup that had a tropical design or logo.

I think that's why I fell in love with Koozys. They were like pieces of reusable artwork that you could take with you to enhance a beverage physically and aesthetically. So, I started collecting them when I would travel around the US. They were small, collapsable, and lightweight making them perfect souvenirs to take home in my overpacked luggage. 

When I moved to Barcelona at the age of 24 I learned that Koozys didn’t exist and I was shocked! Finally, years after setting foot here I’ve decided to start this brand to make amazing designs for memorable occasions to remind people of the places they’ve been and the cold beverages they shared!
