Returns, Refunds & 40-Day Money-Back Guarantee
Our return policy
You may return any eligible product within 14 days of receiving it for a refund — and under our money-back guarantee that period extends to 40 days from the date of purchase. To complete a return we require a receipt or proof of purchase.
These are contractual rights we grant you. They are in addition to, and do not limit, any rights you may have under applicable federal or state law.

Important: To ensure an immediate refund and return process (1–2 business days), please email us the tracking number of your return at support(@)mybollsen.com, or simply reply to your order confirmation email.
Refunds
Once your return is received and inspected, we will email you to confirm receipt and to tell you whether your refund has been approved. If approved, the refund is issued to your original payment method.
Late or missing refunds: If you have not received your refund, check your bank account first, then contact your card issuer — there is often processing time before a refund posts. If you have done all of this and still have not received it, contact us at support(@)mybollsen.com.
Return shipping costs
Shipping costs are non-refundable. If you receive a refund and paid for shipping, the shipping cost is deducted from your refund. You are responsible for the cost of returning the item and bear the risk of loss or damage in transit.
If you are shipping an item worth more than $75, we recommend using a trackable shipping service or purchasing shipping insurance. We cannot guarantee that we will receive a returned item that is not tracked.
Exchanges
We replace items only if they are defective or damaged. If you need to exchange an item for the same product, email us at support(@)mybollsen.com and send your item to the address above. Delivery times for an exchanged product vary depending on where you live.
What cannot be returned
- Sealed hygiene products — items that are not suitable for return for health or hygiene reasons, where the seal has been broken after delivery.
- Inseparably mixed goods — items that, after delivery and by their nature, become inseparably mixed with other products.
- Sealed audio, video or software media — where the packaging seal has been removed after delivery.
- Custom or personalized items — products manufactured or altered to your individual specification.
