I have a 4 oz. bottle (lifetime supply) of Tea Rose by The Perfumuer's Workshop Ltd. There is a batch number and bar code on the bottom of the box, and the batch number on the bottom of the bottle. The spray nozzle is plastic and the cap is silver toned metal that fits quite snugly. I don't know if that's helpful or not, but it's hard to imagine anyone going to the trouble of faking a bottle of Tea Rose. It's so inexpensive and easy to find online.
