3-month Toothbrush / 1.12 Bathroom/Product design

3-month Toothbrush

People usually ignore the habit--change their toothbrushes every 3 months.For the sake of people’s health,we design the 3-month toothbrush.The bottom of the toothbrush handle is a rotatable structure. There are 12 scales on it representing 12 months and also a lock.You can rotate to choose the started month of your toothbrush and toggle the lock button to fix.3 months later,you will know it is time to replace your toothbrush.When you change your toothbrush, you just need to change the head of brush, so that the brush handle can be used continuously.To some extent,it is cost-saving and account for the concept of sustainability.
