I have a bunch of this stuff that I got from a studio that closed and I want to sell it and try to finance some artpanels. It appears to have once been 2'x2' panels since that's what I found
on the internet when I looked up prices, but these have been cut (at the crease in the wedges) into 16"x24" and 8"x24" Pieces. My rough count without digging them all out says I have 25 of each. here's also at least one piece that was cut across the wedges into a 16x12 piece.
They are in pretty good condition on the front except for some small holes at the corners (again, in the crease) where they were mounted with screws and washers instead of adhesive. See pics below...
These sell new for $17.95 per 24x24 panel individually or $179 for a 12 pack ($15/ea.) at most places I saw. I'm thinking $6 for each 16x24 panel, $3 for each 8x16 panel, or $8 for a pair. (to make 1 24x24 panel) I'll do a 12 pack (of pairs, so it would be like the $179 kit) for $80. Shipping is extra, but since this is foam it should be pretty cheap. Local pickup welcome.
Here are some pics. You can see the edge where it was cut and the markings from the washers as well as the small holes from the screws. Some are slightly better, but this is what most of them look like.
