Purchases made through Zelverin™ are processed in United States Dollars (USD).

Does Zelverin™ store my bank card details?

Zelverin™ does not store complete credit or debit card details on its own servers. Payment information is processed through the applicable authorized payment provider.

Shipping & Delivery

How long does order processing take?

Standard order preparation takes 2–4 business days before dispatch. During holidays and other busy periods, processing may take up to 5 business days.

How much does shipping cost?

A flat shipping fee of $5.99 applies to each order, regardless of destination.

What are the estimated delivery times?

Estimated shipping transit times after dispatch are:

  • United States: 10–15 business days.
  • Canada, United Kingdom, and Australia: 11–16 business days.
  • Rest of World: 15–20 business days.

These timeframes are estimates, not guaranteed delivery dates. Order processing takes place before the transit period begins.

Are customs duties included in shipping?

International shipments are sent on a DDU (Delivered Duty Unpaid) basis. Applicable customs duties, import taxes, or clearance fees are the customer's responsibility.

Customs processing may also affect delivery schedules.

Tracking & Package Issues

How do I receive tracking information?

After dispatch, a shipping confirmation email will include your tracking number.

Why is my tracking information not updating?

The tracking system may require 1–3 business days after label creation before the first shipping updates become visible.

A short delay in tracking information does not necessarily mean the parcel has been lost.

What happens if my package is lost?

If the shipping carrier confirms that your package has been lost in transit, a replacement will be arranged without an additional shipping charge.

What should I do if my order arrives damaged?

Contact us promptly and provide photographs showing the damage within 72 hours of delivery.

A replacement will be arranged at no additional charge under the applicable shipping policy.
