These  Vintage 1920's Toggles are very different.  There are two holes in the black body portion of the toggle and as you can see in the above photo, the metal top screws off.  The bottom appears to be made of Bakelite?, plastic? or some other medium?.  They have original tags marked "Czecho Slovakia".  The gold top piece has a black cabachon set in it.   These toggles measure 70mm long and are 9mm at the top and then taper down to a point. There are three of these unique toggles per lot.  Let your creative genius loose on these.
