Store and protect eight Micro SD cards, four SD, and four CF cards in the onyx Gepe All-in-One Card Safe Extreme from Gepe. A well-designed case, it is watertight with an IPX7 rating, and floats in water for easy retrieval if dropped. In addition, the Safe also provides dust, static electricity, humidity, and impact protection. The Safe features clear windows for viewing contents, and a clasp closure that is easy to operate while wearing gloves. To remind them of how many empty cards are left, many photographers will store them with the label up for empty, and label down for full. Made of polycarbonate, with a reinforced hinge and stainless steel pin, this crush-proof case is strong and durable.
