Thank you for viewing this item. This is an SD card reader made by I-O Data. I am selling it because I no longer use it. It is a USB Type-A card reader compatible with SD cards and microSD (TF) cards. While there are no functional issues, please be aware that it has been handled by someone else, so there may be some shine or scratches from use. Thank you for your understanding. Please feel free to comment if you have any questions or requests for additional photos. #SD card reader #IOdata #I-O Data
