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. There are a ton to choose from to make your sign truly personalized.
The size is 23″ x 14″ x 1/2″. Whatever you can fit in there can be carved.
