A set of 10 minature liquid-filled compasses, perfect for a variety of science experiments, especially those involving magnets. Also makes a great inexpensive prize idea for science classroom contests. Each compass has a diameter of 0.75 inches and a height of 0.25 inches. Black base and white markings make taking readings on the go easy.
Note: These compasses may contain a small air bubble. This is normal and does not impede the compass function.
