My masks have not moved. Why are my masks sitting in the same location for a week?

Your tracking update may show that your package is in one location for up to 1 business days. This typically will show that the package is shipping out from a USPS Partner facility to the USPS dispatch center. This is normal and you will still receive your package within 3-8 business days from the order date.

If it is stuck in the same location for longer than 2-5 business days, please do not hesitate to contact us via our email

Why is my order only showing it has been pre-shipped for so long?

Last week of April, we went out of stock and some orders are shipped from our international warehouse due to the high volume of orders.

This should take roughly 7-10 business days for your order to ship from the USA and for you to receive updates on your order.

 Please be patient. If it takes longer than 12-14 business days, feel free to contact us via our email

Who pays for the customs duties & taxes for orders outside of the USA?

Shipments outside of the USA may incur customs fees depending on the destination country. The fee may vary depending on your order value, country limits, and other factors based on the product itself. Your are responsible for these fees. Any fees are paid to appropriate customs agency by the end customer.

Customs agencies often calculate duties/fees based on the declared retail price.

With live shipping rates, orders to Canada generate an Int’l Economy Duties paid with tracking option (4-8 business days after fulfillment). This method can be useful for tracking packages so that they are less likely to get lost in the mail.

Why is my tracking number invalid?

Sometimes tracking numbers may not work because the fulfillment company assigns an incorrect tracking number as a result of processing a high volume of orders.
