Tuners - Gotoh, Classical Guitar, Engraved Solid Brass

Question:
What kind of posts/rollers do these have? Can they be used for a slotted head steel string? Thanks.

Answer:
They are plastic with what appears to be a copper colored inner post. They have an approximate 10mm diameter. Typically, steel string acoustics with slotted headstocks will use some type of metal post, but we wouldn't go as far as saying that these can not be used for that application.
