Mathos Loreley's teether can be used hygienically because it is not often dropped by wearing it around the wrist, so it can be used hygienically. Also, it is hygienic because the part that touches the mouth doesn't touch the floor with a standable design. It stimulates the child's gums with various specially designed protrusions and fine grooves to help the child's teeth develop when teeth start to grow.
Unlike ordinary baby teethers, it is designed so that the part that fits on the wrist can be placed on the floor, so the part that touches the mouth does not touch the floor, so we considered more hygienic use.
