I could see all sorts of things falling in to them. You may also want to stretch the material before starting, gently plying it with your fingers to help widen its reach. Comprato in occasione di un regalo, ho fatto un figurone ottima vestibilità. I love the light scent; its fresh- and reminds me of scents of random facials Ive had in numerous spas. I can NOT make that claim with ANY OTHER ear Hook(s). (wobei das natürlich Anwendungsspezifisch ist). I have only changed the battery on it once, since owning it (little over 2 months?) , and I use it every single day for upwards of 12 hours a day. It should be pretty sturdy at that point. Perfect purchase! The faux fur material was so slippery on the interior that I slid right out the back on every step.
