Friend has some Corian that he has cut in to approx. 12x12 squares (1/2" thick). He has 24 and can put 5 in a USPS box. He is accepting all reasonable offers. Keep in mind to add the shipping cost of the USPS box. Send me a PM and I'll pass on the info to him. Here are a couple of pics of the corian.
