Description
Unsure about the tube measurements? Check your dimensions with a 3D-printed plastic test tube!
We offer a service to 3D-print your tube in plastic before producing it in metal! The plastic model is not meant to be worn as a chastity belt, but is sturdy enough to be put on so you can check the dimensions. You may even use a belt and some string to simulate how the cage feels when held in place as with the real belt.
Tip styles
3 different tip styles are available: mesh, mesh gradient, andn slot.
Mesh: The perforation of the tube continues on the tip. This style is best to avoid any kind of skin pinching as the holes are small enough such that the skin doesn’t get pushed through the holes. Regular drainage and air flow for drying.
Mesh gradient: If you are worried about drainage, we offer the mesh gradient, where the holes in the tip gradually get larger towards the middle. But be aware that skin might get pushed through these larger holes.
Slot: The traditional slot hole, if you are most comfortable with this style. Probably the cleanest drainage if everything is lined up, however with some access and potential for pinching any skin that gets pushed through the slot hole.
Our recommendation is the mesh as it is best in avoiding pinching any skin, but we will go with any tip style you prefer.
Scrotal slippage
Putting on the cage requires the testicles to go through the hole behind the tube where they sit comfortably close in their natural position. However, it is important to know that because of temperature regulation, the testicles are sometimes closer or further to the body (a tight or loose scrotum, changing several times during a day). The cage does not inhibit this movement. This is a deliberate design choice to make the cage more comfortable. It can therefore happen that one or both testicles temporarily “slip out” of the rails on the side. They may return to their normal position. Just be aware that this is normal. If you are unsure about how this effect feels or if you find it comfortable, we highly recommend trying the cage in plastic first before ordering the cage in metal!
Safety
Please use CAUTION when trying on the plastic cage! While the plastic is somewhat robust and flexible to withstand some force, it can break when put under too much stress. The tube itself is unlikely to break, but the side rails could snap if you e.g. try to sit on the cage. Do slow movements when you fix the cage to your body to avoid sudden breaking. Wear the plastic cage on your own risk; kink-knack will not be responsible for any harm caused by the plastic cage!
How to measure
Measure the length and diameter of your flaccid penis. A caliper works best to measure the diameter. The tube will be manufactured 1 mm larger than your measured diameter to make sure you can insert your penis. Measure the length of your penis from the beginning of the shaft at the body to the tip in a straight line. The tube will be 1 cm shorter than this measurement to give a snug fit.
