Crest 3D Whitestrips Thuis Tandenbleekkit - Doos met 10 behandelingen

I’ve been using one strip set a day after brushing and by day eight my teeth are visibly brighter, even in the back. The ten-day supply is perfect for a quick touch-up before a trip.

The adhesive stays put way better than other strips I've tried, so I can actually talk on the phone while they're on. Ten upper and ten lower strips means I've got a full routine for the week and a half, and by day eight my coffee stains were clearly fading.

Ten days in and my teeth are visibly brighter, which is exactly what the box promised. The strips stuck on well and didn’t make my gums feel raw, so I could keep up with the routine even during my work trip.
