The page says used. Not sure it's safe to trust what might be on there. Too much work to have to safely wipe it before use.

This thumb drive is so bad that I wouldn't buy even if it was new in a blister pack.

I've posted in other threads before but will repeat the main points. The biggest problem is the all plastic construction which impacts performance and durability. The drive always runs warm to hot, even when not under load. If you start doing any sustained large file xfers, say 5GB or more, the drive will become very hot and will start to throttle after a few minutes. It will suspend all activity for around a minute to cool down, then restart, running perhaps 10 - 15 seconds, suspend operation again for another minute while it cools down again, then resume for another 10-15 seconds, repeating the cycle until xfer is complete (if you are lucky). I once did a test of writing a 25GB folder to the drive and it took 37 minutes. Wrote the same file to a Samsung Fit Plus which only required around 8 minutes (both tests were run copying files from a locally attached mechanical hard drive to the the USB drives attached to USB3 ports, meaning the Samsung would likely have been faster from an SSD).
These drives are fragile. If you read the negative reviews on Amazon, you will see that the plastic connector is flimsy and prone to shattering. Mine broke inside the USB port and required me to dig the shards out of the USB port.
Due to my experience with this product, I no longer trust SanDisk.
