Returns

Silicone bands sit directly against skin, sweat, and moisture and cannot be hygienically resold, so they are non-returnable once delivered. The only exceptions are a wrong item delivered or an item that arrived damaged, reported within 24 hours of delivery with photos. See our full Refund Policy for details.
