Phone case companies are already starting to figure out what a case looks like for the coming wave of foldable phones. Spigen is one of the first to work out a design, and it’s shared mock-ups of three products it plans to release for Samsung’s Galaxy Fold.
The cases all share similar designs, with front covers protecting the top and bottom bezels of the 4.6-inch outside display and cutouts for the triple-camera system on the back. There’ll be three models — the Tough Armor, Ultra Hybrid, and Thin Fit — with varying degrees of protection, ranging from a thick plastic case to a translucent wrap. All cases will be priced around $20, and largely made out of plastic and silicone materials, like PC, TPU, and PU.
