We have not classified anti-snoring pillows as personal care or hygiene products. Thus, you are welcome to first test our pillows and to return them within your 30-day right to return. We, however, kindly ask you not to remove any protective film or not to use your own pillowcase during the testing phase. In the event that the returned item is heavily stained (e.g., discolouration and tough or difficult-to-remove stains), we reserve the right to invoice you for any cleaning costs or expenses related to replacing pillow cases.
