Customer Reviews
Good whitening pen, quick delivery
I ordered a Whitening Pen and it arrived pretty fast, took about 3 days to get to me. It works, noticed a difference after a few uses. Easy to apply too.
Love the charcoal powder!
I'm a big fan of natural products, so I was really excited to try Diamond Smile's Charcoal Powder. It came in about 5 days, a tiny bit longer than I hoped but no big deal. My teeth feel super clean and look brighter after using it for a couple weeks. I also grabbed a Bamboo Tandenborstel, which is really soft. Prices are fair for the quality, I'll definitely order again when I run out of the powder!
Great value on the kit
I was looking for an affordable teeth whitening option and decided to try the LED Tandenbleekset. I managed to use a welcome discount code for 15% off, which made it a really good deal. The kit itself was easy to use and I saw some good results, definitely felt like I got my money's worth. Shipping was quick enough, maybe 4 days.

Quick question about discounts. Can I stack an influencer code with, say, the Black Friday deal if it's still running? Wanna get the most bang for my buck.
Hey guys, thinking of getting one of their whitening kits. Does anyone know how long the shipping takes to say, Amsterdam? Need it before a trip next month.
