In the event of a contradiction between these documents, the stipulations of the special conditions and/or the accepted estimate shall prevail over those of these GTCS.

Article 1 – Purpose

These GTCS constitute, in accordance with Article L. 441-1 of the French Commercial Code, the sole basis of the commercial relationship between the Seller and its Clients, who request them via the Seller's website, by direct contact, or via a paper medium.

Their purpose is to define the conditions under which C-3D provides the Client with the ordered Product and associated services. They specify, in particular, the ordering conditions, rates, payment and delivery terms, as well as the ancillary services offered.

In accordance with current regulations, these GTCS are systematically communicated to any Client who requests them to enable them to place an order with the Seller. They apply, without restriction or reservation, to all Products sold and associated services by the Seller to Clients wishing to acquire the Products defined in Article 2, in the absence of a specific written agreement concluded between them in any form whatsoever (e.g., invoice, signed estimate, sales contract, service contract, etc.).

Failure by the Seller to implement any clause established in its favor in these conditions cannot be interpreted as a waiver of its right to invoke it later. In case of doubt regarding any condition, reference should be made to the provisions of the Commercial Code.

The Seller reserves the right to modify the GTCS from time to time based on changes to its services, changes in legislation, or for any other legitimate reason. These modifications will be applicable as soon as they are posted online. Exceptionally, in the case of a subscription made by a consumer, the practices in force in the distance selling sector and the provisions of the Consumer Code will apply. The relationship between the Client and the Seller will always be governed by the latest GTCS in force.
