Track Your Order

Sinful Lashes is not responsible for lost or stolen packages, so please track your package and try to be as available as possible when your order is supposed to arrive. Please make sure to have your packages shipped to a secure location. Once you have received your shipping confirmation, USPS will have the most current information regarding your package. Once International Shipments leave the United States, it is difficult for us to track them.  If your package is lost, we encourage you to work with your postal carrier utilizing the tracking number provided in your shipping confirmation email 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.  


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 10 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.
