You can purchase alignment sticks online or they have similar sticks at your local hardward store.  There were a limited amount of  Titleist alignment sticks produced, but, they were not for sale.

Cathi,

You all should really think about producing some Titleist brand sticks.  I think you could sell a ton of them.  

I agree. I bought 3 from Lowe's (yellow), however, I painted them white/black with a hint of red to show support for the #1 company in golf!, and it doesn't hurt being my old school colors as well!

I've also wondered about Titleist alignment sticks, but I have yet to see some in person.
