I've been buying products from LMI since the 70's, long before the web was around. 
The selection and quality has always been superior, and the pricing reasonable! There are other places I can go to buy materials, but none that I trust as much...

Tie Block

Technically this is optional, but most classical guitars use a tie block. Use bone nut or saddle material if your design calls for a larger piece.
