Price includes international free shipping to the USA in about 30 - 50 days with no tracking. 

Worldwide shipping available but price/delivery time can differ

If you order several or in bulk, the price can be lower!

I have ordered this product and received it in less than 30 days to the USA but the shipping I had used has tracking and that's extra $3 and you can receive it in about 30 days or less.  So, if you are interested in that instead, you can select item C or D. The default shipping is without tracking and can take 30-50 days. The item came folded in a packet and in good condition.  It's not really anti-fog but you can wear it on your head with or without a hat.  I think it gives good protection against outside virus/droplets.
