Used these table number holders at our wedding. They are 3" cubes with
4" black wire from the top. They originally came in just wood
(unpainted), but we painted them yellow. They can be repainted to your
liking easily!
The original cost was $13.50 for 12.
I am selling my 36 for $15. PM for offers/details 
Or $1 a piece.
There are no marks, cracks, or scratches on any of them!
