Thanks, but honestly I will not trust Amazon to deliver legitimate products of anything that is in high demand. The amount of counterfeit garbage in their warehouses is could stock every Walmart in the country twice over. I buy masks from primarily from U-Line with McMaster Carr and Grainger as backups. These are major distributors that have contracts with the actual manufacturers as opposed to an Amazon seller that could be a liar or could be legit but with their products commingled with fakes. Downside is with U-Line I'm always paying full price shipping but /shrug.
