These are checkerboard floor bases! They look awesome when you paint it in a checkered pattern. The detail on the bases isn't deep, but it's enough to indicate spots for painting and make it rather easy. The package should work awesome if you plan on making city/sacral bases for your minis, both fantasy and sci-fi!
Here are the sizes of the bases:
25mm x 5
32mm x 10
40mm x 5
50mm x 2
65mm x 2
