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 Jesse Blair

Certainly well built, it seems to protect SD cards well from inclement weather. Two small things to note: the small rod inside that is used to eject stuck cards is just loose. It should have a special place in the suitcase as it may eventually get lost. Other: This item is quite heavy and a little bulky. So if you're using it for travel or in backpacks and weight is of paramount concern, there may be lighter options.
