To be honest I wouldn't have thought of it,  but a customer did.  Usually we produce the magnets on 0.5mm overall thick material;  however one of our customers liked the feel and look of the 1.7mm foam expanded magnetic material.  We produced 2000 memo boards on this material and to be honest we are very pleased with the result.  If you would like a price on this please don't hesitate to contact us.
