The package remains unsealed, yet the anti-static bag holding the board would be marked as "shut." It seems like a seal exists in name only.
In Brazil I purchased a Gigabyte B450M DS3H V2 (rev 1.0). The packaging wasn’t sealed, though the anti-stick bag for the mobo was. Inside: two SATA cables, the mobo, the shield/mirror, a disc, and some paperwork. My Asus TUF x570 arrived much better sealed, with everything that typically comes with the device. I understand this B450 was a budget model, but it seems a bit careless to skip even a small piece of tape on the box. What a surprise!
