# Open Clasp-Equipped Phone Cases CASEKOO Debut LinKOO with the "World's First Open Clasp System" By Kalin Ned | Published 2026-03-16 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/open-clasp-system References: [tucson](https://tucson.com/online_features/press_releases/article_02f4472b-c2f3-5e14-b0f8-35dea2b6f3a1.html)  [CASEKOO](https://www.trendhunter.com/trends/silver-ease) has introduced a new phone case called [LinKOO](https://www.trendhunter.com/trends/linkoo-collection), which features what the company describes as "the world's first open clasp system." This hinged mechanism at the base of the case can securely hold a chain or wristlet when desired and then fold completely flat against the device when not in use. Thus, the design allows the LinKOO case to seamlessly transition from a hands-free accessory mode with an attached strap to a slim, pocket-friendly profile without any protruding hardware. Aside from the functional open clasp system, CASEKOO's product is constructed with a durable, impact-resistant frame. The innovation is initially available for the [iPhone 17 Pro Max](https://www.trendhunter.com/trends/caviar-magnetic-custom-collection) in a color called Vital Orange, with additional colors and finishes planned for release later in the spring season.
