The first cylindrical magnet has a hollow cylindrical section located at the center of the first top surface. Additionally, a second connecting device has a second cylindrical magnet with a second top surface. The second cylindrical magnet has a cylindrical protruding member located at the center of the second top surface. The protruding section of the second connecting device fits into the hollow section of the first connecting device. The magnetic clasp locks when the first and second connecting devices are brought together allowing opposite magnetic poles to face each other. To unlock the magnetic clasp the first and second connecting devices are rotatably turned allowing like poles to face each other.
