Grandma's necklaces, continued

Based on my last thread and how these look, I doubt they are anything, but want to make sure.

The multicolored green one is marked JAPAN on the hook, are the beads plastic?

The last one, I gather, is a belt? It is about 41" total length and the clasp is big, about an inch! Very 1980s, I guess?

 

Aww, poor Grandma, evidently not much value here either! Can just picture her wearing these, though.

 

The plastic ones don't sell too well, and 1960s multi-strands are seriously off the boil. The last one probably is a belt. If you were to sell them, I'd lot them up and then they might move to a crafter or the like.
