The storage case uses a 2mm-thick aluminum alloy shell that resists shocks and pressure. It features an anti-static EVA foam lining that protects memory card chips from static damage and scratches. The case offers layered storage that holds six SD cards and twelve TF cards for organized access. Its ultra-thin rectangular shape fits easily into pockets or camera bags for convenient carrying. A secure snap-lock closure keeps memory cards secure and prevents them from falling out during accidental drops. - Obasyhig Aluminum Alloy Memory Card Storage Case in Black
