goes to sea with the Terrain Mat.
I found this product at Hobby Lobby, and I'm wondering: does it have a hobby purpose?
This is a set of square coasters, make from thin cork. They measure 4" x 4" and come six to a pack.
The package is theoretically resealable, but it is very flimsy – mine ripped just opening it for the first time.
And here you see them with a 28mm Kryomek figure, to get a sense of scale.
The cork is thin and flexible, rather than stiff.
