This innovative concept was created by young, husband and wife duo, Jeremy and Alissa Huber who reside in Southern California. When asked how he came up with such an ingenious idea Jeremy said, “I just wanted something that was secure for working out, but not so restrictive that I couldn’t change songs. I took the concept of a magnetic ID badge and incorporated it into a plastic case and that is how the original prototype was born.”
The iStik magnetic case is currently available for the 2nd generation iPod Nano. Cases for the 3rd generation Nano and iPhone are currently being designed and will be available soon
