Size and measurements
King Cock Hollow 25 cm: size
The dildo is 25 cm (9.8 in) long, about 5 cm (2 in) less than the long side of an A4 sheet (29.7 cm (11.7 in)), and 4.8 cm (1.9 in) thick, a little more than a ping-pong ball (4 cm (1.6 in)). Inside is a hollow plastic tube 3.8 cm (1.5 in) in diameter.
The product information gives the length of the dildo as 25 cm and, on another line, as 25.5 cm.
Step by step
How to use the King Cock Hollow 25 cm
- Put on the harness: the two straps go over your shoulders, the strap on your waist and the bands on your thighs.
- Adjust the nylon straps until it feels secure without being tight. The shoulder straps take the weight of the dildo.
- Check that the metal ring goes around the base of the dildo and that the Velcro strip wraps around the shaft.
- Decide how you wear it: if you have a penis, it goes inside the plastic tube of the dildo; if not, you wear the harness the same way.
- Apply water-based lubricant to the outside of the dildo and, if you wear your penis inside, to the tube as well.
- Start slowly and let the person receiving set the pace.
Cleaning
Wash the dildo with warm water and mild soap after every use, on the outside and inside the tube. Rinse it and dry it well, inside too, before storing it. Clean the nylon straps with a cloth and soapy water, and let them air dry. Do not boil it or use disinfectants. We have not confirmed the manufacturer's cleaning instructions: this advice is our own.
Our advice
- Use water-based lubricant. With latex condoms, no oils.
- Go slowly: the dildo is 4.8 cm thick. If the person receiving feels pain, stop.
- If you wear your penis inside the tube and notice pressure, numbness or pain, take it out.
- Do not go from anal to vaginal without washing the dildo first.
- Check the straps and the Velcro before you start: the shoulder straps are what carry the weight of the dildo.

Questions
King Cock Hollow 25 cm: frequently asked questions
How big is the King Cock Hollow 25 cm?
25 cm (9.8 in) long and 4.8 cm (1.9 in) thick. Inside the dildo is a hollow plastic tube 3.8 cm (1.5 in) in diameter. We have not confirmed how much of the length goes in or how deep the hollow is.
Is the King Cock Hollow 25 cm hollow?
Yes. It has a plastic tube 3.8 cm (1.5 in) in diameter set inside the rubber dildo. According to the product information, anyone can wear it this way, including a man with erection difficulties, with the penis inside the tube.
Is the King Cock Hollow 25 cm adjustable?
Yes. The shoulder straps, the waist strap and the thigh bands are nylon and adjustable. A Velcro strip goes around the dildo to hold it. According to the product information, the waist strap fits most sizes; we have not confirmed the maximum waist size.
What is the King Cock Hollow 25 cm made of?
The harness is nylon and metal, and the dildo is rubber with a plastic tube inside. According to the product information, the dildo is phthalate-free.
How is the dildo held on the King Cock Hollow 25 cm?
With a metal ring that keeps it in place. Four metal strips fix that ring to the base of the dildo.
Is the King Cock Hollow 25 cm suitable for starting out with a strap-on harness?
It is not a starter size: the dildo is 25 cm (9.8 in) long and 4.8 cm (1.9 in) thick, a little wider than a ping-pong ball (4 cm (1.6 in)), and the product information presents it as an extreme-size strap-on harness. It makes more sense if the person receiving already uses dildos of that thickness. We have not confirmed how firm the rubber is.
Which lubricant should you use with the King Cock Hollow 25 cm?
Water-based. We have not confirmed what type of rubber the dildo is made of, and water-based lubricant is the one that suits any material and latex condoms. Apply it to the outside of the dildo and, if you wear your penis inside, to the tube as well. This is our own advice.
How do you clean the King Cock Hollow 25 cm?
With warm water and mild soap after every use, on the outside and inside the tube. Rinse it and dry it well, inside too, before storing it. Clean the nylon straps with a cloth and soapy water. This is our own advice: we have not confirmed the manufacturer's instructions, so do not boil it or use disinfectants.
