Ideal multicoloured UV reactive fibre optics for multisensory environments with the added safety of a pmma fibre core. The absence of electricity in the polymer fibre tails makes them completely safe to touch. As well as producing the same sparkle effect as the standard sensory harnesses the tails in these harnesses also glow dramatically under UV black light. Please note that as the tails are already coloured they don t change colour but the intensify of the colour does change. Our harnesses come 150 tails x 2m as standard. If you would like alternative number of tails or length measurements please contact us for a quote. All harnesses are fitted with a standard 30mm common end for connection to a fibre optic light source. For indoor use only. The PVC in these harnesses is phthalate free and the harnesses themselves have CPSIA and EN71 toy certifications so you can be sure you are purchasing a safe high quality UK made product. Lightsource available separately.
