I am a long-time fan of Luxey, who like so many has to resist the urge to purchase every new color. There was something about Happy that just kept drawing me in (even though I had the intention of purchasing Fallon). When my silicone set arrived, it was better than I imagined. You cannot look at Happy and not feel like warm sunshine. This is what I love about Luxey - you don't need to purchase a whole new cup just to experience a different color. You can mix and match till your heart is content just by purchasing the silicone. Happy = owning a Luxey Cup and helping to keep Mother Earth Happy too!
