Are you unable to pick up your purchase yourself, or is an item too large to transport yourself, for example? Then use a specialized courier.
Important: Always contact the seller first about your purchase and the transport possibilities. Also ask if the seller can provide (light) packaging such as a layer of bubble wrap. Only then can you make a good choice for a suitable courier service.
Please note: large transport services such as DHL, FedEx, UPS, are not specialized in art transport and often require extensive packaging.
