Package theft is on the rise. If you are in an area where packages are being stolen we recommend that you put a “hold on packages” with your local USPS office and pick them up from there. If you are unable to pick up packages and prefer that they are delivered, please add SIGNATURE REQUIRED to your shipping (available for both flat rate and free shipping) to ensure you receive your package. Sinful Lashes is not responsible for stolen packages (those packages shown as delivered but you did not receive them). 


Sinful Lashes processes orders Monday through Friday, excluding major US holidays.

Orders will be processed within 1-2 business days. Orders placed on Saturday and Sunday will begin processing the following Monday. 

The COVID-19 pandemic has affected USPS SHIPPING times. Some orders may take longer then our typical 1-3 days. We are working diligently to process and ship orders as soon as possible so please be patient with us as we are all in this together.

Track Your Order

Sinful Lashes is not responsible for packages marked “delivered” and are  stolen. Please track your package and try to be as available as possible when your order is supposed to arrive.  Please also make sure to have your packages shipped to a secure location. If you feel that your location is not secure please add “signature required” to your order. Once you have received your shipping confirmation, USPS will have the most current information regarding your package. If your package is lost, we encourage you to work with USPS for compensation. If you discover your shipping address is incorrect on your order confirmation, please email us at immediately to correct the address so we can ensure you package is sent to the correct location. Packages are picked up daily by 12:00 PM (PST). After a package leaves our facility it is impossible to make changes to the shipping address.

Product Availability

In the unlikely event that an item becomes out of stock after your order is submitted, we will ship the rest of the items in your order and send you an email indicating that one of your selected items is out of stock and you will be refunded for that item.  


Due to the Covid-19 pandemic we are unable to accept product returns at this time due to health and safety concerns. Please ensure that you received the correct product upon delivery (or pick up). If an incorrect item is shipped to you, it will be replaced at no cost. Please contact us immediately if that happens so that we can make things right. Please note: after 7 days of delivery (or pick up) the item can no longer be replaced. 

Your satisfaction is our number one priority. If in the unlikely event there is a defective product or quality concerns beyond your control, please contact us at for returns within 7 days of delivery to receive a refund or exchange. A return label will be provided. After 7 days, the product is nonrefundable. Defective products or products which you have concerns on quality must be returned unopened and unused in order to receive a refund or exchange of product. Due to our inability to gauge how adhesives are stored once they leave our possession, adhesives cannot be returned or exchanged after 7 days. 

If you are unhappy with your unopened and unused products and wish to return or exchange them, you can do so for up to 7 days from delivery for a full refund or exchange. All refunds will be credited back to the original payment method. Sinful Lashes is not responsible for covering these shipping costs.

Clearance items are available in limited quantities. If a clearance item is unavailable, we will refund the cost of that item to the original payment method. All sales on Clearance Items are final. There are no returns or exchanges. All sales on “on sale” items are final. There are no returns or exchanges.
