This is a Meditarranean cedar, very white with lots of curly grain around knots. 18-24" wide x 9' long x 2" thick. There are also some 3'x5' which make great tables. They smell great and the smell remains if you use them inside without a finish. Outside, I would put a marine varnish on them.
Weather resistant, insect resistant. Without a finish, ages nicely to gray outside. With a marine varnish finish, will look like new for years.
