Definitely a 9oz Jar!
Every other website I've ever gotten this exact jar from lists it as 9oz. Only on here is it listed as 12oz. It's a bit annoying because I sell these as 9oz and other sellers have the exact candles listed as 12oz. I can only fit around 8oz of wax and scent, so this should definitely be listed as 9oz.
Other than that it's a great jar!
