The idea for torus objects comes from a museum.

Thin versions of torus objects look like artificial hair.
Thick versions of torus objects look like artificial berries.
The difference between torus frame and torus pearl is the hole.
Torus pearl has a hole and it's diameter is between 3.5 - 4.0 mm.
Slight variations depending on materials.
Different sizes S and M have still the same hole diameter.
Types 4, 6 and 8 have the hole in different places.
Then the patterns on pearls are also different.
There are photos showing the types.
Size S is about 10mm.
Size M is about 20mm.
