The tube of the Spark is made of TPU material (thermoplastic polyurethane) and thanks to the Anti-skid 3D Design technology it offers two different hardness levels. The anatomical orthodontic mouthpiece, reduced in size and made of hypoallergenic silicone, has excellent hydrodynamics and is rotatable, so that it can be placed at the right angle for comfortable and long-term use. Additionally, its attachment with the silicone "8" ring does not exert unnecessary pressure on the side of the head or ear.
