How to select the ring diameter ?

Most of our customers use the 45mm diameter ring. However, other diameters are available. The following is a 4 steps procedure to help you determine the right diameter for you.

Take a 30 cm (12 inches) long string and place it around your scrotum and penis. Remember not to use an elastic string, as this would alter the measurements.
Make a double knot : the string should be tight enough to make it difficult for you to slip a finger under it, yet not so strong as to cut off the blood flow. Leave the string on for 5 minutes.
To make sure it is the right diameter. Cut the string with a pair of scissors, taking care not to hurt yourself while doing so.
Measure the length of the string and consult the following chart to see which one is the right diameter for you.

Length mm	Length inches	Ring size
110 to 118	4.33 to 4.67	Ø 36
119 to 132	4.68 to 5.2	Ø 40
133 to 148	5.21 to 5.82	Ø 45
149 to 163	5.83 to 6.41	Ø 50
164 to 180	6.42 to 7.03	Ø 55

Characteristics of the resin

What is biosourced resin and why use it for a male chastity device ?

Our chastity devices are made of biosourced resin from sustainable resources (plants), in replacement of chemical and petroleum products.

This resin combines properties that have never before been brought together, for example, transparency and resistance to impacts, as well as a slower rate of development of bacteria.

The resin is very resistant to chemical agents. It contains no solvents, no petroleum-based products and no cadmium or heavy metals
The resin is not classified as toxic
The resin demonstrates antibacterial qualities slowing the growth of bacteria into direct contact with the skin, mucus membranes or tissue. The resin is odorless and induces no allergic reaction
The resin contains no bisphenol, latex, phtalates, etc...
The resin is very resistant to pressure and has good mechanical qualities
It is very resistant to chemical agents, solvents, oils and water
The resin is resistant to UV rays
Even though the resin comes from natural products, it doesn’t wear away or decompose over time

Recommendations for use and care

You may use any type of lubricant, water-based, silicone, those composed of plant or animal oils. The chastity device may be left in the sun, however, it will tend to turn slightly yellow if you expose it over a long period.

The chastity device changes its structure when exposed to temperature changes. At a temperature of 20°C (68°F), the device will be hard like rugular plastic. At 36°C (97°F), it will become slightly silken, which will provide extraordinary comfort for the person who wears it. If you take a very hot bath without removing your device, it might become almost as soft as silicon. However, its resistance to tearing will be lessened. It is thus strongly recommended to avoid bending or compressing the device when it reaches a temperature that is higher than body temperature. The resin can endure temperatures of up to 150°C (300°F); it can therefore be put in a dish washer or be sterilized.

Placement of the chastity device

The HolyTrainer has the particularity of having a tube that is attached to the ring. Placing the penis and the scrotum in the ring is very easy. The tube is then placed in the ring, guaranteeing a firm attachment and totally enclosing the member from the bottom of the abdomen to the end of the penis. Since the tube is placed in the middle of the ring, no pinching of the skin can occur.

1) Insert the ring by pulling the skin of the scrotum until the testicles is fully inserted

1) Insert the ring. Pull the skin of the scrotum until the testicles are fully inserted

2) Insert the penis into the ring

3) Lightly lubricate the tube and insert the penis and slide the tube inside the ring

3) Lightly lubricate the tube and insert the penis and slide the tube to inside the ring

4) Lock the Magic Locker and remove the key

In conclusion

Biosourced resin satisfies expectations within the framework of sustainable development with alternative products and processes that are more respectful of man and his environment.
