It could hold three European type plugs but I did not test it so I have no idea if it would still work. Also it might not be safe to use as it probably doesn't meet today's safety requirements.
But it's a great piece to own anyways as it would be a fun addition to any mixed media creation :-))
Lovely rose and greenish colors.
Meas. approx. 44x32x37mm. Two little cracks on one side (see last picture)
***Please note there may be some slight imperfections due to its vintage nature and being part of the charm of this item.
