I purchased this to solve my iPhone's storage shortage, but it's been sitting unused. This allows you to connect memory cards like SD cards and microSD cards to your smartphone for reading and writing data. I'm selling it because I changed iPhone models and can no longer use Lightning. One item has been used once. The one that was used does not have the plastic packaging that protects the product. The other three items are unused, but one box is slightly torn from checking the contents. Therefore, I have lowered the rank for this listing. Please consider purchasing only if you understand the above. (*^^*) This is a set of 4 items, so I've made it cheaper than listing them individually to save on shipping costs. These items have been stored by a non-professional for a while. Please refrain from purchasing if you are concerned about minor details. m(_ _)m
