SanDisk Extreme microSD card boasting 1TB and a maximum read speed of 190MB/s Brand: SanDisk Model: Extreme Capacity: 1TB Thank you for viewing! I purchased two 1TB cards for a month-long overseas trip, but one was sufficient, so I'm selling the unused one! I had no issues using it during the trip ◎ This product was purchased from the Karneval Shop website, and I bought it because it had good reviews compared to those on major, well-known sites. Please read the reviews before purchasing if you are interested! Also, although it is unused, it has been taken out of the package once, so please understand this before purchasing.
