The cushion like my wife, it's only about 2 mm thick and 12 cm long

The cushion is only about 2 millimeters thick and 12 cm long including 2 cm Velcro closure so that it has 10cm circumference and exactly fits well to a normal Krückstockgriff. I like my wife well. To the slightly thicker handles her crutches by the health insurance it does not fit, is too short. She has the crutches handles now coated with a baby sock.
