Caviar has begun selling custom versions of the foldable iPhone Ultra, even though Apple hasn't yet officially unveiled its first foldable smartphone. The company's designers relied on leaks and engineering prototypes of the future device.

The most unusual version is the Liquid Metal version—its case is made of silver and polished to a mirror shine, and the design references the image of liquid metal from the film “Terminator 2”. According to Caviar, the company has prepared 10 design options for the future iPhone Ultra, using leather, silver, gold, and titanium.

The foldable iPhone itself remains an unofficial Apple product for now. According to recent leaks, it could be unveiled as early as September, alongside the iPhone 18 Pro and 18 Pro Max. A foldable, book-style body is expected, with an internal screen measuring approximately 7,8 inches and an external screen measuring approximately 5,5 inches. There have also been reports of the possible use of a "liquid metal"-based alloy in the hinge—a durable material unrelated to actual liquid metal.

Caviar's custom versions are priced significantly higher than the expected price of the smartphone itself. The company lists the iPhone Ultra Titanium version starting at 13 840 USD, Silver at 15 270 USD, Dark Cherry at 14 270 USD, and Gold at 15 560 USD. By comparison, the standard foldable iPhone Ultra, according to current leaks, could cost around 2 000 USD–2 500 USD.
