Candle by The Hour 60-Hour Candle Refill, Eco-Friendly Natural Beeswax with Cotton Wick

What is the diameter of spiral wax? (I'm on the listing for 60 hrs). I bought one at an estate sale, and I don't know what size refill to purchase.

Does this candle have option to refill?

Does this come with a glass shade?

Do these come with any other metal finishes? Nickel? Black? Anything?
