4. International Shipping

We ship to eligible international destinations. Available international shipping services, shipping charges, and estimated delivery times vary by destination and are displayed at checkout.

For eligible international orders, applicable import duties and taxes are calculated and collected at checkout where required. When these charges apply, the order is shipped on a duties-and-taxes-paid basis so that the same import charges should not be collected again at delivery.

International delivery estimates may be affected by carrier operations, customs processing, local holidays, weather, or other events outside normal transit conditions.

5. Tracking

When tracking is available, you will receive shipment confirmation with tracking information after the order has shipped. Please allow up to 48 hours for tracking information to become active after the carrier receives the shipment.

6. Address Accuracy and Changes

Please review your shipping address carefully before submitting an order. If you notice an address error, contact us as soon as possible. We will try to help before shipment, but an address change cannot be guaranteed once fulfillment or carrier processing has begun.

Additional carrier or re-delivery charges resulting from an incorrect or incomplete address may be the customer's responsibility where permitted by law.

7. Delayed or Lost Shipments

If your shipment has not arrived within the estimated delivery timeframe, please contact us. We will review the tracking information, work with the carrier when necessary, and assist with an appropriate resolution based on the circumstances.

Delivery estimates are not guarantees and may be affected by carrier delays, weather, public holidays, customs processing, or other transportation disruptions.

If an item arrives damaged, defective, or incorrect, contact us within 7 calendar days after confirmed delivery. Please include your order number and clear photos of the item, packaging, and shipping label when relevant.

This Return & Refund Policy explains when a return is eligible, how to send an item back, who pays return shipping, and how approved refunds are processed.

1. Return Window

You may request an eligible return within 30 days after confirmed delivery. Return requests submitted after the 30-day period are not accepted unless applicable law requires otherwise.

  • Unused, unwashed, and in its original condition.
  • Returned with the original packaging, tags, accessories, manuals, and other included components, when applicable.
  • Not specifically identified as final sale or non-returnable before purchase.

Products that show use, alteration, avoidable damage, missing components, or other conditions outside the eligibility requirements may be ineligible for a refund.

3. Product-Specific Non-Returnable Items

Some products may be non-returnable for hygiene, safety, customization, final-sale, or other product-specific reasons. Any such restriction will be disclosed on the product page or before purchase when applicable.
