Today I bought Colgate zig zag black tooth brush of rupees thirty. The colour of this brush is of black and blue color. At the back of brush tongue cleaning action is also given. This brush moves forward and background. Multi angle cross bristles reach deep teeth to effectively remove plaque. But colgate can do much by introducing coupon code or promo code for paytm as well. Colgate brush also launch health insurance procedure becaush tooth problem is worst. Byju's course with colgate not work because the scheme is only limited to specific age group children and I don't think any body gets benefit of it.
