Review on Streamline Your Space with PUNCUBE Holder: A Minimalist Organizer with Blocking Capabilities by Bart Schwalbe

As another reviewer mentioned, this slim wallet/card holder is poorly designed. The plastic key compartment separates easily from the main card holder, the plastic latch feels tacky and poorly constructed (think: Pez dispensers). The card case itself feels cheap and although it is very thin it is too wide, it can easily be narrowed down. Returned immediately.
