External dimensions: 120mm wide x 85mm long x 30mm deep Internal dimensions: 110mm wide x 60mm long x 15mm deep The clasp is magnetic. The "Kitamura" logo is inside and not visible from the outside. It comes with the original box, but it's not in very good condition. As you can see from the size, it's a somewhat awkward size. I bought it for a heated tobacco device, but I quit smoking, so I'm selling it without using it. Please check the size before considering a purchase.
