GIGASTONE Micro SD card 128GB microSDXC A1V30 U3 C10. Purchased new and opened, I tried to use it in a Yupiteru drive recorder, but it didn't work due to an error. It was recognized by a PC, and I could write and read data. I formatted it and put it back in the package, but the package is taped. I don't know much about it, so I'm selling it. It is also being sold elsewhere, so please understand if it sells out depending on the timing.
