Our team aims to get your order out as fast as possible. Due to this very small window of time, we may not be able to "catch" your order before it is in the mail.Generally, no changes can be made once an order is placed. If it's been less than 15 minutes, please email us at hello@bewellow.com with the subject "CANCEL ORDER" along with your full name and order #. We'll respond on a case by case basis.
