You can put the belt on and off without removing it from your pants. The toilet doesnt remove the belt every time, so it is convenient to take it off. The size of the belt can be adjusted, so it can be used even when your child grows. Even if you have a big waist bottom, the elastic will fit your body gently. To use, simply pass through the belt loop and secure the front hook in two places.
