All original artworks are varnished with a protective layer before shipping out. Stretch canvas can be fragile, be careful not to put sharp objects on the back to avoid uneven bumps on the front. Simply use a semi-dried cloth to clean off any dust if needed. However, some pieces with gold pigment requires delicate care as pigments may fall out or drop over time.
