Due to the nature of Tatti Lashes products and for hygiene reasons, they do not provide refunds/changes for undesired/changed ideas. If you receive a damaged or defective item, they will of course replace or refund you. Please note that their eyelashes are handmade with love, so each eyelash may be slightly different, although this is only small, this is not a malfunction, but a part of the unique eyelash allocation of their staff to a single hair.
