Suitable for the trendy Megasmile Sonic Black Whitening sonic toothbrush, two replacement brushes are available in a double pack. Newly developed special bristles with activated carbon granules remove discolouration without the use of bleach or toothpaste with abrasive cleaning bodies. The original colouring of the black brushes with neon contrasts brings a breath of fresh air to any bathroom. The bristles are available in medium thickness and therefore suitable for almost all users. For regular brush head replacement, there is always a replacement brush at hand.
