frT beldo User Guide (2025)
frT beldo is a restoration device that uses a flexible cord to stretch the skin. Like a belt, the cord wraps around the desired body area (waist, knees, legs, shoulders), creating a tension that provides flexibility.
– Parts of the device –

- frT cone (1 piece)
- Transparent holder (1 piece)
- Standard beldo cord (1 piece)
- Ring (1 piece)
- Softening rubber (4 pieces)
- Excess elastic (3 pieces)
Cone and transparent holder

The cone is placed over the head of the organ. The function of the cone and the transparent holder is to hold the skin in place and connect it to the cord. The skin is fixed by being placed between the cone and the transparent holder. The ring at the top of the cone is used to connect the flexible cord.
The cone, which is placed over the head of the organ, is covered with skin. The skin is manually peeled back and the cone is covered with skin. A transparent holder is then lowered onto the skin. This fixes the skin between the cone and the transparent holder, trapping it in place. The fixed skin is now ready for tension application.
Standard beldo cord
The standard Beldo cord is a flexible cord that fits all waist sizes . Its adjustable length allows it to adapt to different waist sizes and different usage styles.
The “Y” type beldo cord has 3 separate ends:
- Wrap-around end (removable big hook)
- Cone end (fixed hook)
- Excess end (double-layered end)

Use of the cord
After the cone and transparent holder are attached, one of the two hooked ends of the cord is first attached to the cone ring. The other hooked end is then wrap around the waist and threaded back into the cone ring, thus attaching the device.
The two most common uses for the Beldo cord are wrapping it around the waist or the leg. However, the end of the cord that is wrapped is important. When wrapping the cord around the waist, wrapping the first end ensures that the adjustment point is closer to the navel. The big hook at this end makes it easier to grasp and wrap. Therefore, it is recommended to wrap this end.
Adjusting the cord
There are two ways to adjust the tension the device applies to the skin:
- Lengthening/shortening the cord
- Slide the cord
The length of the cord is adjustable to suit all waist sizes, different wearing styles, and desired tension level. The cord can be lengthened or shortened using the adjustment point on the cord.


The “excess end,” the hookless end of the “Y” type cord, allows for this adjustment. The excess end and the fixed hook end are connected. As one lengthens, the other shortens, and when one shortens, the other lengthens. It is possible to shorten the cord length by lengthening the excess end through the adjustment point. This allows the cord to be used with greater tension. Lengthening the fixed hook end lengthens the cord, reducing the tension the device exerts on the skin.
Tension adjustment
It’s recommended that users new to restoration begin with a low initial tension. This is because the skin needs time to adapt to the tension. For a low level of tension, simply adjust the cord slightly shorter than the user’s waist. Over time, the tension can be increased by shortening the cord.

Another way to adjust the tension is to slide the device across the body while it’s being worn. This allows for adjustments without changing the cord length. To adjust the tension with this method, you can slide the cord left or right, or up or down, depending on where it’s being used. You can also adjust the tension by sliding the cord.
Direction of insertion of the cord
The surface of the cord that touches the body is important for user comfort during use. To prevent excess end from getting pressed between the cord and the body and causing discomfort, the excess end should be on the side of the cord that doesn’t touch the body. With this in mind, the cord should be wrapped correctly around the body.

Collect the excess end with a rubber band


Depending on the usage and tension level of the cord, the excess end length may become uncomfortable for the user. In this case, the excess end is folded and collected with the elastic bands provided inside the device. Because the excess end is thicker when collected with elastic bands, it is more important for comfort to prevent it from getting pressed between the cord and the body. Therefore, it is beneficial for the user to become familiar with the correct orientation of the cord, as mentioned above.
Extra: Cut off the excess end
Some users may want to keep the cord permanently short, depending on the intended use or desired tension level. In this case, the excess end can be cut off, as it will be ineffective. However, extreme caution should be exercised when doing this.
If the excess end is cut off more than necessary, it will not be possible to lengthen the cord when desired. Therefore, the maximum length of the cord that will be used throughout the restoration process must be determined first. Then, the first cut is made at the “end of the excess end that enters the adjustment point (i)”, leaving a 10cm (4″) stretch from the adjustment point. Then, the second cut is made at the “end of the excess end that extends to the big removable hook (b)”, leaving a 2-finger-wide allowance from the seam. This completes the cutting process.

After the cutting process is completed, the ends of the cut areas should be sealed by burning them with a lighter to prevent the cord from unraveling.
Tilting the organ to the right or left

The direction in which the cord wraps around the body is important. The direction in which the cord wraps applyer less tension on that side of the skin. This difference in tension between the different sides of the skin depending on the direction the cord is wound is not significant. However, the cord can sometimes be wrapped in opposite directions to balance this difference.
For example, if the user is to wear the device for four hours a day, the organ is tilted to the right for two hours and the organ is tilted to the left for the remaining two hours. This way, the tension applied to both sides of the skin is equalized.
Softening rubbers
Softening rubbers are generally used in the initial phase. While the Beldo device is in place, the cone is in contact with the head of the organ. Pain may be felt for a while until the head of the organ adapts to and tolerates this contact. It takes time for the head of the organ to become accustomed to the cone. Therefore, softening rubbers should be used until the head of the organ becomes accustomed to the cone.

Softening rubbers can be used in different quantities and placements depending on need. Some examples of how the softening rubbers are placed on the cone are shown in the image.
– Cleaning and maintenance –
The parts of the frT beldo device that require regular cleaning are the “cone” and the “transparent holder.” This is because these parts are in active contact with the skin during use. Therefore, oil and dirt residue from the skin contaminate these parts over time. The transparent holder, in particular, can lose its grip over time due to contamination. Therefore, it must be cleaned regularly to maintain its functionality.
When cleaning these two parts, you can use hot water up to 40°C. It is recommended that the flexible cord be hand-washed at 30°C or wiped with a damp cloth. You can also clean it under warm water with hand soap.
