I ordered the wrong thickness and the return shipping is way too expensive. I have a new case of 12 sheets of 1/2″ x 40″ x 60″ white non-archival foam core, in the case, brand new. You can buy the case for $275, or by the sheet for $23. The price I am asking does not include the shipping I paid, it is just the cost of the panels. Text me at 917-375-7362 if interested.
