Conventional toothbrushes usually do not clean as thorough as you expect because there are areas that they cannot reach. The CARICH Charcoal String Cleansing Toothbrush is made with very fine strands that can solve this problem. It captures and removes debris or food residue that are stuck. It is also very strong and durable, allowing it to scrap off any stains that have accumulated for a long time like tobacco marks and such. Comes in 2 pieces per pack, it helps to reduce bad breathe with its all-round cleansing process.
