I deliver the parcel by DHL. Delivery terms are different, it all depends on the city and country where you live. Approximate delivery times are 6-20 days, after all necessary documents for export have been completed. Delivery at my expense. I will deliver the picture in a plastic tube, it is more reliable.
Only shipping is free, taxes in different countries are different, they are all at the expense of the recipient.
Returns at your expense within 7 days. In my experience, no painting has been damaged during delivery. DHL works quickly and efficiently.
