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 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.

The key Insertion and use of the "MagicLocker"
The chastity device comes with a locking system « MagicLocker » that slides through the ring & tube to holds them together. The « MagicLocker » is tightly adjusted. If you find it difficult to insert, you can always use some lubricant or put the ring & tube under warm water.

It is important to verify and test the locking system before you put it on. The « MagicLocker » has to be inserted without applying too much strenght. Before turning the key it is important that the « Magic Locker » is all the way in. Then turn the key clockwise to secure th system. The key will be released only when the system is closed.
