ProGrade SD card. Purchased officially on Amazon. Used about twice. I'm selling it because I switched from SD cards when I bought a new camera. I'm also selling another one of the same card. 【High Data Transfer Speed】 ProGrade SD cards boast a maximum data transfer speed of 250MB/s, making them ideal for shooting high-resolution photos and 4K videos. 【Large Capacity Storage】 With a large capacity of 256GB, you can store a lot of data, which is convenient for long shoots and data backups. 【Reliability and Durability】 Compatible with the V60 standard, it offers high reliability that can withstand professional use. - Brand: ProGrade - Capacity: 256GB - Speed: 250MB/s - Type: SDXC UHS-II - V60: Supported Feel free to comment.
