Think Tank Pocket Rocket
This green Secure Pixel Pocket Rocket from Think Tank can hold 6 CF, 6 XQD, 12 SD, or 12 micro SD memory cards inside its see-through slots. My favorite feature of this memory card case is that each row of memory card slots features a zippered closure for enhanced security.
While the Secure Pixel Pocket Rocket can be used to keep memory cards protected and organized inside a larger bag or case, its belt loop and detachable lanyard allows you to put your memory cards within immediate reach. I keep mine secured to an interior pocket inside my Shimoda Designs Action X50 backpack
The Secure Pixel Pocket Rocket's exterior is woven from water-repellent nylon for durability as well as weather resistance, and features an ID sleeve that may be used to display a contents label or owner information.
