MVP, Axiom, and Streamline share one set of plastics, so they’re filed together here. Neutron is the opaque premium and the biggest line on this site; Proton the clear premium; Plasma the soft, metallic-sheen blend; Electron the baseline, sold in Soft, Medium, and Firm.
Eclipse is the glow, Fission the microbubble lightweight, and Prism is the Axiom-only plastic with a Proton rim and a variable core. Cosmic Neutron is a swirled run and lives on the Neutron page.
