Shopping Neck donuts

Hi!

I am looking for resin neck donuts for 1/3 dolls--the kind that can help a head sit higher on a neck, or help with s-hook attachment inside a head with a key mechanism, not the kind that just works to hold an s-hook on a headless body. Normal skins preferred, but I'll look at anything. What companies/dealers offer these? Thank you!

 

@StellaMarigold What I'm looking for is similar to that, except smaller and sits on top of the neck. That one would be nice if the neck were too big, but I'm just trying to give the neck a bit more length, or use it inside the head for heads not really made to use s-hooks. But thank you anyway!

@AlisonVonderland I miss Mint on Card so much. I do remember they had exactly what I want, and I'm pretty sure I bought several from them. They were my favorite dealer.

And for reference, here is what I'm looking for:

 

Thank you so much!!
