MABS (Methyl Methacrylate-Acrylonitrile-Butadiene-Styrene)
This thermoplastic offers high strength and impact resistance, though not quite as strong as standard ABS. But unlike ABS, MABS offers high transparency, and can display very bright transparent colors and glitter effects. Since around 2018, LEGO has switched to using MABS for most transparent parts instead of PC. It tends to look slightly milkier than older transparent parts, but I believe this is improving as LEGO continues to refine the material.
