Oral-B iO replacement brush heads, 4-pack, with 100% plaque removal power with the new brush. I accidentally bought the wrong shape. I just bought them a few days ago. They are brand new and unused. I want to sell them at this price, so I will also include a brand new, unopened PC cream (whitening cream). - Brand: Oral-B - Model Name: iO - Quantity: 4-pack - Color: Gray - Features: 100% plaque removal power with the new brush Thank you for looking.
