Stem only source?

[alled]

I've gotten a few keycaps and sets that have a clear plastic stem epoxied to the back of the keycap.  One example of this is the KBDFans wooden keycaps.   Does anyone know where I could get those plastic stems?  They're clearly being mass produced somewhere, but I'm not finding a source.

My bet is that they're being ordered somewhere from China, was thinking of just contacting some of the sellers on like Alibaba and asking directly but following this if someone has better suggestions.
