Help Identifying the maker of this Flex Chain necklace. HELP

I can’t seem to identify the maker of this chain. It appears to be similar to Magic Flex. Please, please help. The hallmark is an M with a script L next to it. TIA Darryl :unamused:

That doesn’t look like a hallmark to me, it could be a shops mark.

If there are no other marks it is not english so i can’t help i’m afraid.
