This is made of Starboard- the stuff used for those plastic feeling cutting boards… It’s absolutely weather proof- it won’t fade, peel, warp, or crack, and it’s not easy to break. They’ll last forever under sea water, in direct sunlight, in freezing cold, or all the above at the same time!
These guys are 1/2″ thick and consist of two colors- one sandwiching the other.
The size is 21.5 x 9.5″ x 1/2″.
You can order without an acrylic lens or with an acrylic lens for a nominal upcharge.
