Ie; the actual silicone device without bonding threads/casing?</p> <p>If so, this is unfortunately not on our product list, but send me a PM with your location and I&#39;ll give you the contact information to the Nordic sales manager in our area. If this is something we can provide, they&#39;ll know.</p> <p>Cheers, Håkon</p><div style="clear:both;"></div>
