Product photographs and descriptions are as accurate as possible but have no contractual value.

Prices are shown in euros, all taxes included, as well as in satoshis (Bitcoin equivalent, converted at the rate in effect at the time of order). Delivery fees are specified before the order is confirmed and are added to the price of the products.

Souverain XXI reserves the right to change its prices at any time, it being understood that the price shown at the time of order is the only one applicable to the customer.

The order is confirmed once payment has been received. Accepted payment methods are:

The order is only considered final once full payment has been received.

Article 5

Delivery

Products are shipped to the address provided by the customer when ordering. Delivery times are indicative and include, where applicable, a production time (for made-to-order products): allow around 10 to 20 days between order confirmation and delivery.

In the event of a significant delay or a damaged product on receipt, the customer is invited to contact us via our contact form.

Article 6

Withdrawal, returns and refunds

Right of withdrawal (14 days)

In accordance with articles L221-18 et seq. of the French Consumer Code, the customer has a period of 14 days from receipt of the product to exercise their right of withdrawal, without having to justify a reason. This right applies to all our products, except for any items personalized at the customer's request.

To exercise it, the customer must contact us via our contact form, stating their order number. The product must be returned unworn/unused, in its original condition. Return shipping costs are borne by the customer, unless the error is ours. The refund is issued within 14 days of receiving the returned product.

⚠ Legally sensitive point — to be validated before going live

Modification or cancellation before shipping

The customer has 2 hours after confirming their order to contact us regarding any modification (address, size, color) or cancellation. After this period, or as soon as the order has been sent to our manufacturing partner, production has started and the order can no longer be modified.

Defective or non-conforming product

In the event of a defective product or one that differs from the order, the customer has 10 days to contact us via the contact form, with a photo or video of the issue. We ask customers to contact us before any return, as we do not have a storage warehouse.

Lost or unclaimed package

Package lost in transit:

For products manufactured and shipped by our on-demand production partner, they cover reshipment or refund if the package was never delivered and the address provided was correct, provided we report it within 25 days of the estimated delivery date. If the carrier indicates that the package was indeed delivered, this case is not covered by our partner; we will review the situation on a case-by-case basis.

For products we ship ourselves, in the event of a confirmed loss in transit and if the address provided was correct, we will also review the situation on a case-by-case basis.

In all cases, if the address provided by the customer was incorrect, the loss cannot be covered.

Unclaimed package:

For products manufactured and shipped by our on-demand production partner, if the package is returned (not collected, address not found), the customer is contacted and has 30 days to request reshipment (at their own cost). After this period, the package is considered abandoned and can no longer be resent.

For products we ship ourselves, if the package is returned, the customer is contacted and has 21 days to request reshipment (at their own cost). After this period, the order is considered abandoned.

Article 7

Legal warranties

All products benefit from the legal warranty of conformity (articles L217-3 et seq. of the French Consumer Code) and the warranty against hidden defects (articles 1641 et seq. of the French Civil Code), independently of any commercial warranty.
