These just arrived at my domicile and I was a little incredulous at first. The iPorter by ePorter is a tiny SD card holder made of plastic. That's all well and good. It's shaped like a little digital camera, which is kind of dopey, and it's on a little ring for easy addition to your key ring, which is highly unlikely. I figured there would be some foam in there or something and just hold the cards. But I snapped the case open and found a little fanning group of SD card holders, three in all, which ingeniously hold SD cards.
Am I truly amazed? Naw. But I have a few SD cards and I just found me a place to put them all! Priced at $9.95 for a pack of two, I can unequivocally state that they can hold SD cards—and even xSD cards, little pieces of paper, and used fingernails—quite efficiently.
