I saw your post about needing skulls from time to time for for your line of work, so I thought I send you a quick message.
I have a small skull shop and do excellent work...museum quality. If you are interested, please check out my website www.pure-bones.com where I have a decent photo gallery. I'm also on Instagram @pure_bones with lots of photos there too.
Let me know what you are looking for and I'll be glad to help you out. If I don't have a particular skull in stock, I can probably get it for you.
