MAD Yupo Pre-made Artboards are made in the porthole design, the top is 6mm MDF with 22mm sides.
We use real YUPO !!! We also use a 1 ton vacuum sealed press, this presses the Yupo down hard and tight , giving a perfect working surface. This means that they are ready to paint on, and you can seal the board after painting. They are also even strong enough to cover with resin , then an easy hang on the wall.
No more need to do expensive framing for your Yupo pictures, its now easy.
