These beautiful pendants are made by Yellow Goat.
Make sure you the cord allowed is enough for your project, if you have a high or raked ceiling like this house you should request extra length.
Much easier to have too much cord than not enough.
I am not sure if they Sell to the public, but you will be able to find suppliers on their website.
