I use professionally primed belgian canvas "Claessens". On the massive 3D stretcher width 4 cm. The sides are always spotless white. This provides a good view of any environment and this makes it possible not to use an additional frame.
All paintings are ready to hang up on the wall.
Wooden crate for transportation done on a professional machine for each painting on size. Pre-packed in bubble oilcloth for extra protection.
An authenticity certificate is attached.
