When did phone cases first come out?

Phone cases first emerged in the early 1990s, shortly after mobile phones became more widely available and portable. The earliest cases were often made of leather or hard plastic and were designed primarily for protection. As mobile technology advanced and phones became more varied in design and size, the range of phone cases expanded significantly in the late 1990s and 2000s. Today, phone cases come in countless styles, materials, and functions to cater to diverse consumer preferences.
