The Crystal Jellyfish is built to break the "transparency vs. feel" dilemma. The Problem: Dim & Muted RGB Standard opaque or frosted housings swallow up LED light and scatter it poorly, leaving your premium keyboard lighting looking dull, patchy, and compromised. The Problem: Mushy & Hollow Feel To achieve a clear housing, many transparent switches compromise on materials, resulting in a soft, mushy bottom-out and a cheap, hollow, rattly sound. The Problem: Dust & Rapid Decay Open-stem clear switches easily invite dust and crumbs. Once debris enters, the aesthetic is ruined, quickly leading to scratchiness and double-clicks. ✨ Kailh Crysta
