The special protective case for the Ulefone Armor 21 keeps the surfaces of your valuable phone looking like new. In addition to protection, it offers excellent carrying and attachment options for the phone, as the special case is equipped with removable attachments: a carabiner, a belt clip, and a carrying strap. You can choose the appropriate attachment mechanism depending on the situation, allowing you to secure the phone to your belt, clothing, or backpack, for example. In everyday life, you can leave off the additional attachments when carrying the phone in your pocket.
