CASEKOO, a leader in innovative mobile lifestyle accessories, has announced the launch of LinKOO, a groundbreaking phone case featuring the world's first open clasp system. Designed for the vibrant energy of spring, LinKOO allows users to effortlessly switch between a secure chain-carry mode for hands-free convenience and a compact traditional case for slipping into a pocket or bag.

Why it matters

The open clasp design of the LinKOO case represents a unique innovation in the mobile accessories market, offering users greater versatility and personalization options to match their spring wardrobes and lifestyles. As consumers seek products that can adapt to their evolving needs, the LinKOO case provides a transformative 2-in-1 solution that balances style and functionality.

The details

The magic of LinKOO happens when the chain comes off. Engineered with a patented clasp at the base of the case, it securely holds a chain or wristlet to complement any spring look. But the true innovation is that the clasp folds completely flat against the phone when not in use, instantly transforming from a statement accessory into a sleek, pocket-friendly case. LinKOO is constructed with a durable, impact-resistant frame and available in a range of fresh, seasonal colors and finishes to match any spring wardrobe.

  • LinKOO is now available in Vital Orange for the iPhone 17 Pro Max.
  • A full range of colors and finishes will be rolling out in late May 2026.
