What is source and price of this material ?

From what I read so far, I don't see a benefit yet. "carves like butter, paints like wood" ... melts like ?
Data reads 5# density. not so hot.  Also I noticed it says water based regarding paint. Dunno about anything like dope or automotive, lacquer based paints.

Will it melt if you use iron on covering?  I think  I will wait to see if anyone else tries it and reports...
