Refund and Returns Policy
Shipping & Returns Policy
Shipping
All orders are shipped via USPS Tracked Mail from our U.S. fulfillment partner.
Tracking information will be provided by email once your order has been dispatched. Most domestic orders arrive within 3–5 business days, though delivery times may vary depending on location and carrier performance.
Please ensure your shipping address is entered correctly at checkout. Once an order has been fulfilled, we’re unable to modify or redirect it.
If your tracking number shows “delivered” but you haven’t received your package, please contact USPS directly to file a claim. We are not responsible for lost or stolen parcels once delivery is confirmed by the carrier.
