These 360 gsm semi-gloss postcards are out of this world. The Quality is outstanding and you are not bound to use them as postcards, you are also able to use them as art prints and put them in a frame. 
The back is completely blank so you don't have pre-drawn lines that will limit the amount you can write on these which I find always a bit annoying on normal postcards. 
This way, you can decide, how much space you want to give for specific sections.
