Hi Stefany
I mentioned the size in a message following under my first reaction as "Size beads", but here they are again:

Size of beads:
Crab right, diam 15 mm. perf 4 mm.
Crab left, diam 13 mm. perf 3 mm.

Fruit, diam 13 mm. perf 3,5 mm.
Dragon, diam 15 mm. perf 3 mm.

I think they were not part of the Chinese zodiac, because the fruit and crab don't belong in there.
I rather think that drawings on the beads are good fortune signs.

stay healthy, Hans
