Review on JJC Camera SD TF Micro SD Memory Card Case Holder Organizer Box with Card Removal Tool & Lanyard - Water-Resistant Storage for 4 SD & 4 TF Cards by Edward Freeland

This little bag is the perfect size, not too big, it fits in the palm of your hand. Holds 4 micro SD cards plus 4 SD cards when you insert micro SD cards into SD card adapter. then it effectively holds 8 micro SD cards. I personally use it to store 2 x 128GB micro SD cards and 2 x 32GB GoPro camera cards, which is a lot of storage space. I tested the water resistance by placing a square of paper towel the size of the interior on top. immerse in the hull and fully submerge the hull for 10 minutes. The paper towel was 100% dry. You can confidently take it on a kayak or water trip and keep your SD cards dry. Overall, I highly recommend this little bag, I'm definitely happy with it.
