This filter feels like a pocket-sized portal to another dimension. The top swirls with galactic green nebula clouds, like cosmic storms drifting through the void. Beneath, a shimmering violet base is speckled with crushed star-dust, glowing like a distant galaxy cluster under the pull of a telescope. Flip on a UV light, and the top erupts into an alien-green radiance — like a pulsar beaming through the cosmos.
