The second series of 4 insects from 1991 is better known than the first. In addition to their appearance, they are distinguished by their logo engraved on each character. The first round would be 1976, and it’s still very difficult to find.
WARNING: Many of these insects are sometimes offered for sale but are key chains with ring removed (see below).
There is also a small key-key character, just from the United States (see below)
The Raid Insect is a Johnson Company Brand
