2PC 30D 프로 화이트닝 젤 듀오 (단품 구매)

I’m only a week into the 30-day routine and already noticing my teeth look less dull in photos, especially around the edges. The pen-style applicator is precise enough that I don’t waste any gel, and the two tubes mean I’m not scrambling for a refill mid-month.

The pen-style applicator makes getting the gel onto my teeth so much easier than those messy trays, and I'm already noticing a difference in my smile after just a couple of weeks. Two tubes is perfect for the full 30-day routine.

I was skeptical about at-home whitening, but after two weeks with these 1oz tubes, my coffee stains are noticeably lighter, and the gel glides on mess-free. The duo is a solid value, and I've got plenty left for the full 30-day run.
