My eight-year-old granddaughter, Eden, found an empty dental floss container. She opened it up and found that inside, there was an empty spool, which she put a fake diamond ring on. When she showed it to us, we saw that Oral B could sell refill spools, saving consumers money and saving the planet. We contacted Oral B, did an online chat, and the rep thought it was a great idea. He’s taking it to his team. I hope that more kids come up with ways to save our planet. She was thrilled!
