A great way to keep your partner locked-up in their restraints for at least two hours with no letting go. The instructions are simple. Just fill the open end with water, insert the other piece inside it and place it in the freezer for about two hours. When you remove it from the freezer it is a solid block of ice inside the encasing that will not let the two pieces apart until the ice melts. Hook the rings on the two ends to any chain or restraint you like and keep your sub locked and bound until the ice melts. Depending on the room temperature, this can be up to two hours, so make sure you are prepared for this amount of time being locked in! Made with quality stainless steel, this item will not rust and will be great for play, time after time. It’s a new, fun way to play with bondage and discipline!
