Hey guys! I've been looking all over the internet for the past like 45 mins or so but I just cannot seem to find what I'm looking for. I recently bought this model kit (apologies, I know it isn't megami device but I'm not sure where else to turn as I can't find any info about these other than a few youtube videos and the Amazon listings, and the seller won't respond to me unfortunately)

As It turns out, the wrist joints on this is actually very weak and I've already broken 2 of them. Luckily, they give you 6 pairs of joints with this kit but I'm now using all of them as it also includes 2 fully bodies, both with 2 wrists each of course. Anyway, I'd just like to buy more joints for these as I'm worried I'll break another joint, in which case I'm not sure what to do other than buy another kit but I'd rather not do that atm.

TLDR: Where buy wrist joint that will work for the linked kit?

Thank you for the help! :)
