Most Caluniva™ orders are prepared within approximately 2–4 business days. During holidays, New Year periods, or unusually high order volume, processing may take up to 5 business days.

We currently apply a flat shipping fee of $5.99 per order, regardless of destination, unless a different shipping arrangement is clearly shown at checkout.

Estimated delivery times after dispatch are generally:

United States: 10–15 business days
Canada / United Kingdom / Australia: 11–16 business days
Other supported destinations: 15–20 business days

Delivery estimates may be affected by carrier schedules, customs processing, weather, public holidays, and local delivery conditions.

Once tracking information becomes available, it may be sent to the email address associated with your purchase. Tracking activity can take approximately 1–3 business days to appear after a shipping label or tracking number is generated.

Tracking systems do not always update in real time. A package may continue moving between facilities even when no new scan appears. Please allow a short period for the carrier system to refresh before contacting support.

Address changes should be requested as soon as possible. Please email service@caluniva.com within 12 hours of placing your order. Once processing has progressed too far, we may be unable to make changes.

Cancellation requests should also be submitted within 12 hours of purchase. Because orders may enter preparation quickly, cancellation cannot be guaranteed after processing begins.

Payment options shown during checkout may include PayPal and supported credit or debit cards. Available methods can vary according to location and payment provider.

Caluniva™ orders are processed in United States Dollars (USD). Your bank or payment provider may apply currency conversion or international transaction charges where applicable.

Caluniva™ does not use complete credit or debit card details as ordinary store account information. Payment authorization and transaction processing are handled through the applicable payment provider or payment gateway.

Eligible products may be returned within 30 days after delivery. Products should generally be unused, in the same condition received, and returned with original packaging or tags where applicable.

Please contact service@caluniva.com before sending an item back. Include your order number, the product involved, and a short explanation of the reason for return. Return instructions will be provided if the request is approved.

No. Please request authorization before returning a product. Packages sent without prior instructions may not be correctly identified or accepted.

Once an eligible return is received and approved, the refund is generally issued to the original payment method. Please allow up to 10 business days for processing. Your bank or card provider may require additional time before the credit becomes visible.

Contact us as soon as possible and include your order number, a description of the issue, and clear photos of the item and packaging. If possible, please report visible shipping damage within 72 hours of delivery so our team can review the situation.

If the shipping carrier officially confirms that your parcel was lost in transit, contact our support team with your order and tracking details. We will review the shipment and provide the appropriate next steps, which may include a replacement.

International shipments may be sent under DDU (Delivered Duty Unpaid) terms. Customs duties, import taxes, or other destination-country fees, where applicable, are generally the customer's responsibility.

Certain products may be excluded from standard returns, including personalized items, perishable goods, some hygiene or personal-care products, hazardous materials, gift cards, and items identified as final sale where applicable. Contact us before returning an item if you are unsure.

In many cases, the simplest option is to return the original eligible product and place a separate order for the preferred item after the original return has been accepted.

We aim to present products as accurately as reasonably possible. However, slight differences in color or appearance may occur due to lighting, photography, screen type, brightness settings, and device configuration.

Depending on product availability and destination, orders may be fulfilled through selected manufacturing partners or fulfillment facilities. Different items in the same order may occasionally follow different fulfillment routes.
