Heavyweight watercolor paper meets functional postcard design in blocks of twenty cards ready for painting and mailing. Van Gogh crafts these from 200gsm acid-free stock that handles wet-on-wet techniques without buckling or bleeding through to the postal side. The surface takes multiple washes and lifting without pilling, giving you the control needed for small-scale landscape studies or spontaneous travel sketches.

Each card features standard postcard formatting on the reverse, address lines, stamp placement, message space, printed to postal specifications. Paint your image, let it dry completely, add your message, and drop it in the mail. The paper weight meets international postal requirements while providing enough body to protect your work during transit.

These blocks work particularly well for plein air painting sessions where you want to capture quick impressions and share them directly rather than photographing finished work. The compact format encourages decisive brushwork and thoughtful composition within constraints. Studio artists use them for color studies and technique experiments that become gifts rather than filling drawers. Paint what you see, write what you feel, send what you made.
