When will it arrive?
Shipping and delivery times for products entrusted to the courier vary from 1 to 5 business days.
Deliveries are made Monday through Friday.
Delivery times are purely indicative and are in no way binding. Shipments are handled by external couriers (e.g., Poste Italiane Group, SDA, GLS, BRT, UPS, DHL, MailBoxes, etc.), so we cannot guarantee a specific delivery date, only an approximate timeframe.
Deliveries are subject to undetermined variations during holidays, unexpected or planned carrier strikes, shipment management issues with the courier, or significant weather conditions.
Deliveries may be delayed if the shipping company encounters management issues: e.g., misdirected shipments to other regions, lost shipments, adverse weather conditions, locations not served daily, delays during the Christmas period, delays during the Black Friday period, etc.
