A cool current of ocean blue and seafoam green swirls across this filter like tides colliding beneath moonlight, each line softened by the sandblasted matte finish that gives it a smooth, frosted feel. The blasted surface mutes the shine and lets the colors feel deeper—almost like worn sea glass pulled from the shore. Under UV, the entire body erupts into a vivid radioactive green, transforming the calm water tones into something wild and electric. The matte texture gives the glow an almost ghostly diffusion, like bioluminescence suspended in motion.
