The perfect companion, this extremely loyal ally will always be by your side when you need him most! Indeed, this unique crossbreed will cling to its owner and follow their lead wherever they may go.

Having expertly adapted from its predecessor, the Knot, this all-new breed of animal is a much more sociable creature that appreciates affection from more than just one person. Indeed, it will do anything to please and always goes the extra mile. Let him off the leash and allow him to explore further afield to see what he is really capable of! Expertly attuned to our human ways, the Knot Sheath not only follows orders, but also instinctively knows what we need. In addition, he has been expertly trained to detect places that ordinarily cannot be found, pinpointing them with 100% accuracy.

The Sinnovator Knot Sheath Platinum Silicone Penis Extender has been expertly designed with the same dogged determination and unparalleled attention to detail as all other Sinnovator creations. Indeed, it showcases all the same exquisite design detail as the Knot Dildo, but with some added extras! Complete with pointed tip, raised veins and a bulbous knot, it also features a fur texture towards the bottom of the shaft and a ball loop at the base that is designed to look just like a leather collar with intricate needlework and a buckle fastening. However, this ball loop is intended for much more than its stunning aesthetics; it will keep the sheath in place for the duration of wear.

Measuring 9 inches in insertable length and 10 inches in circumference at its widest point, this fine quality cock sheath adds invaluable inches and unique texture to the penis. In addition, there are 3 internal size options to choose from for a customised fit. Expertly designed using advanced 3D print technology, the Sinnovator Knot Sheath is hand-poured from premium platinum silicone that not only feels sensational, it is body safe, non-toxic, phthalates free and compatible with all your favourite lubricants.

Signature Colour: The Sinnovator Knot Sheath showcases a stunning bronzed rose gold and deep woody burgundy to really draw out the dimensions and realistic features. The rippling colours of the silicone wraps the product in flecks, and streams of darker accents draw out the beauty and elegance whilst also enhancing the shape and contours. Choose ‘signature colour’ above to add this masterpiece to your collection.

Sinnovator - How It's Made

Step 1: Mix

Step 1. Mix. Crafted just for you, your Sinnovator creation requires a specialised mix of oils and powders to ensure the correct colour and firmness. The ingredients must be accurately measured, stirred, and placed in a vacuum chamber to eliminate gas and bubbles prior to pouring.

Step 2: Pour

Step 2. Pour. Handcrafted clay sculptures form a structure for the moulds into which the specialised silicone mix is poured. Every customised creation is painstakingly hand poured by skilled artisans, who create a steady stream of silicone that gradually fills the mould and creates a luxurious marble effect.

Step 3: Pack

Step 3. Pack. Once the silicone has set, your tailor-made Sinnovator creation is expertly removed from its mould and beautifully packaged in a resealable, clear fronted bag. Passionate about their work and adding that extra personal touch, our craftsmen will then use a label to sign and date your artwork.

Step 4: Deliver

Step 4. Deliver. Simply place your order before 12pm and your item will be despatched within 48 hours. 100% discreet, there are no company details or indications as to what is inside your parcel and the strong, protective packaging ensures your Sinnovator sex toy reaches you in the very finest condition.

Made in the UK

Your Sinnovator toy is created in our workshop in the UK and is made of materials that are all 100% produced in the USA. We only use platinum silicone, which is a premium quality, body safe material instead of the old favourite, vastly inferior rubbers, vinyls and plastics.
