I have a YOYOJAM Mini Motu from a trade. It has been used and the caps were taken out and flowed silicone was put in. It works great. Plays like a larger throw due to the 69 gram weight. I do not have the caps. I contacted YYJ and they said they do not have any either.

I am just looking to get a plastic throw that is a little heavy in trade.
Thanks for looking.
