Where can I buy these great lucite legs??

I would like to use these sculptural lucite legs for newel post finials. Who manufactures or retails them. I can think of more and more uses......

Check out Lucid Bespoke for custom lucite legs.

Where can you find the acrylic legs that are posted?

You could firstly check with local fabricators then DIY furniture accessories stores. If you need only a few they might charge you custom fee.
