The Booq Mini Folio for iPad Mini 4 magnetically combines folio and polycarbonate iPad mini case. An insanely versatile design that merges the protection of a snap case with the benefits of a multi-fold folio. Folio's polycarbonate case attaches to its multi-fold folio via an ingenious super-array of magnets, making the two seemingly inseparable parts divorceable. This level of craftsmanship makes you look good.
