Each postcard is 3mm thick and can actually be posted (in an envelope though) with a first class stamp as it will fit through the standard letter slot at the post office and weighs less than 100g
We use the highest quality Birch Plywood and once we have done all the lasering we hand sand everything to give the wood a great silky smooth finish.
This also removes the horrible burn marks and burnt wood smell that the lasering process produces.
