Nexpaq is the first modular smartphone case that allows you to seamlessly customize, enhance, and add new functions to your existing smartphone through the use of small squares, called modules.

You don’t even need to turn off your phone when adding modules.

Simply slide them in to the back of the case to give your smartphone extra powers like more battery, a stronger speaker, or new sensing capabilities and exotic functions you never thought possible.

Nexpaq is currently available to for:

• iPhone 6 and 6 Plus
• Galaxy S5, S6, S6 Edge, Note 4, Note 4 Edge
• OnePlus One
