Summary: This holder is built very solidly. I believe it would survive being put in a back pocket and subsequent sitting upon. The slots hold the SD cards firmly. It provides an excellent way to organize SD cards which might be otherwise lost in drawers.
Summary: I store pics on SD cards and keep them in this card case, as it holds 8 cards. It works great, but am a little concerned about how it snaps closed. It is strictly for storage in my case, so not too worried, but I would be more concerned if I planned on taking it on the go. My mom has a zip closure case that holds 8 cards as well and seems a little more secure in its closure.
