Buying or trading mummy/ mommy charms, charmkins

[Petaurus]

Hi,
I've just started to collect the mummy charms, and charmkins ponies.
I'm interested in buying, but also have a few duplicates that I'm willing to trade.
i don't mind buying a few more duplicates that are in good condition.
I will put up a list of the particular ponies that I want later as my collection progresses, but for now anything that you have I will be interested in

One mummy charm that I am particularly interested in is Laugh a lot. She is yellow with pink hair.

Thanks for taking the time to read this
Cheers everyone
