Thank you for viewing. Two PHILIPS Sonicare C2 replacement brush heads designed to reach the back teeth. - Brand: PHILIPS - Model Name: sonicare C2 CleanPlus - Type: Electric toothbrush replacement brush heads - Quantity: 2 - Features: Design that easily reaches back teeth - Size: Standard - Bristle Stiffness: Medium - Brush head recognition function compatible - No pets, no smokers Originally, it was a set of 5 genuine brush heads, but I switched to a different toothbrush manufacturer, so I'm selling the 2 unused ones. Of course, they are new and unused, but the box has been opened boldly (see photos). They will be shipped in the box, sealed with tape. If you don't need the box, I can discount it by about 100 yen, so please comment. In that case, I will pack them simply with cushioning material and ship them in a zip-lock bag. Thank you for your consideration.
