I purchased this at the pop-up event in Kobe last month. I will also include the sticker that was distributed at the pop-up. Unfortunately, this product didn't agree with my skin and caused a breakout, so I'm reluctantly selling it. I've used it 4 or 5 times, but I didn't use my fingers; I used a soft, squishy brush. Please refrain from purchasing if you are sensitive to used items.
