Starbucks' Winter/Christmas Holiday Mystery Box Topper (2024) --- Blue Poinsettia/Flower Brand New/Never Used Material: Silicone The Poinsettia/Flower topper is 1 of 6 possible toppers you can pull from their first ever, mystery boxes. All mystery boxes bought in stores, are unknown until you open them, as the SKUs are identical. And there are no external identifiers on the boxes to indicate which one is inside. So if you don't like lottery systems/gatcha games, or you still haven't scored your poinsettia flower topper, there's always this one!
