Bell older for issuing magnetizable !. Objects

The invention relates to containers for dispensing objects, in particular metallic objects such as Paper clips, hairpins, nails, etc. that are easily magnetizable.

Known magnetic containers of this type have certain Disadvantages, which consist in the fact that the objects are in bundles or chains due to the magnetization stick together so that the user needs both hands to remove an object from the container at a time. and put the rest back into the container.
