Der Tiefentrainer

The Cum Tube Upgrade adds a silicone tube running along the entire length of the toy, connected to a syringe filled with liquid (water or lubricant). Apply pressure to the syringe, and voilà – the liquid expels through the toy's tip. A syringe is included, but you’ll need to purchase the lubricant separately.

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 offer the following firmness options:

Medium Firmness - 10A on the Shore hardness scale
Super Soft Firmness - 0040 on the Shore hardness scale
Squishy Soft Firmness - 0020 on the Shore hardness scale

For more information about our firmness options see our firmness guide.

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.

Check out our colour guide to see exactly what our colours look like. But please keep in mind, each toy is hand-poured, so no two are exactly alike!
