Parfum de Voyage atomizer?

Does anyone have any idea why they discontinued these travel atomizers? I just picked one up on eBay and I am really impressed with it so far. Really cool aesthetic for a travel atomizer, and being able to customize it is great.

Going to have to find some more second-hand. I’m just bummed they don’t officially sell them any more.

Does anyone have any long-term experience with how these hold up build-quality wise?
