Guess what came in the mail today?

Ordered the bone nuts from eBAy on Jan 3rd 11pm, it shipped Jan 5th arriving Jan 11th today.  USPS International service was used.

Here's what they look like, already marked with slight cuts for the strings and flat ready for gluing back to the headstock. 

Now there's the question of which glue should I use for the nut to the headstock neck area?

Any opinions?

Now I really need a set of strings so I can measure the nut and saddle heights before gluing.
