has a painting service do Space Marines.
Here's something I recently spotted in the craft aisle at Dollar Tree:
This is described as a peel-and-stick sheet of 'disco' (mirror) tiles, 5mm square. (There's also a large tile size.) The sheet can be cut to give you a smaller number of tiles.
Above, you can see what the sheet looks like.
And here is a 28mm Kryomek figure to give you a size comparison.
Would you use these for your wargaming projects? Solar reflector? Shaving mirror? Skyscraper? Magical mirror? Alien spaceship?
