These fun sensory neon noodles have varying textural finishes, some being knobbly, and some with ribs going either horizontally or vertically. They make excellent sensory aids as they are bright and colourful, super stretchy, and have interesting textures. The pink, yellow, orange, and green ones also fluoresce brightly under UV blacklight. They make a cool sound when spun around too, hard to describe but like helicopter propellers or the beating sound of a swans wings when flying. Six Neon Noodles27cm LongSuitable for 3+ years
