You Probably Won't Be Able to Get Apple's New Polishing Cloth in Time for the Holidays - MacRumors
The $19 "Polishing Cloth" that Apple introduced alongside the 14 and 16-inch MacBook Pro models has proven to be wildly popular, and it is now sold out until the end of December/early January.
Orders placed today have delivery estimates ranging from December 20 to January 17, so those who hoped to purchase one for use with their new MacBook Pro or another Apple device will need to wait for two to three months.
Made from a "soft, nonabrasive material," the cloth is suitable for Apple displays, including the nano-texture glass of the Pro Display XDR.
