The Made To Measure Tentacle Knot Extender

Don't worry, your extender isn't going anywhere once it's on! And here's why:

First off, when you slide it on, it works a bit like a magic trick. It traps some air inside, creating a suction effect that keeps the extender snug and secure.

Second, because this isn't a one-size-hopes-to-fit-all situation, your extender is tailored to your exact measurements. It's like it's been custom made just for you (because, well, it has!), ensuring it fits perfectly and stays put, no matter what you're up to.

Choosing a made-to-measure penis extender over a one-size-fits-all option is all about customisation. The truth is, no two penises are exactly alike, making it pretty unlikely for standard extenders to fit everyone just right. That's where these bespoke extenders come in. We tailor each one to your unique measurements, ensuring a perfect fit every time. It's the difference between wearing a suit off the rack and one that's been expertly fitted just for you.

We offer 6 different colour styles, though not all are available on every product.

Surprise Me Basic - Leave the decision in our capable hands and we'll choose a solid colour that compliments your toy selection. 

Surprise Me Premium - Leave the decision to us and we'll get creative with two or more colours. We love this choice as it allows us to get experimental with all of our colours, often resulting in our best pours. 

Solid - One colour that will run evenly throughout your toy

Fade - Two colours combined that are gradually blended together. Colour 1 will be the tip of your toy and Colour 2 will be the shaft and base. 

Marble - Two colours combined resulting in a veining effect similar to classic marble. 

UC Trademark - This is a product-specific colour. The main image of the product is the UC Trademark colour.

We use platinum silicone so you get a toy that is non-pourous (meaning when you clean it, it gets fully clean and can't transmit bacteria), doesn't smell, is body safe and feels fantastic.
