The popularity of Apple's iPhone means there's a very healthy accessories market to support it. But not all of those accessories are official, and one line of iPhone cases is now being recalled because they can cause skin irritation, chemical burns, or even permanent scarring.

The cases are known as "liquid glitter iPhone cases" and were manufactured in China and distributed by MixBin Electronics LLC, of Hamilton, N.J. They come in a range of designs and were sold by Amazon, Henri Bendel, MixBin, Nordstrom Rack, Tory Burch, and Victoria's Secret stores from October 2015 through to June 2017. Consumers paid anywhere from $15 to $65 for each case.

According to the US Consumer Product Safety Commission, the liquid and glitter can leak out of the plastic casing and cause harm. Some people simply get a skin irritation, but in the worst cases chemical burns occur which leave permanent scarring.

In total, some 263,000 glitter cases were sold across the US, with a further 11,400 in Canada, and 400 in Mexico. Cases were offered to fit the iPhone 6, iPhone 6s, and iPhone 7, with 20 different designs available.

In total, 24 reports of skin irritation or chemical burns have been reported, with 19 of those occurring in the US. In one case a woman experienced "swelling to her leg, face, neck, chest, upper body and hands," in another, "permanent scarring from a chemical burn."

The advice, as you'd expect, is to immediately stop using the glitter cases and to contact MixBin Electronics for a full refund. This can be done by calling MixBin toll-free at 855-215-4935 between 8am-5pm ET Monday-Friday. MixBin also created a dedicated page for the recall giving full details as well as images of all the different case designs.
