These ear weights fit in ears stretched to 20mm and over. The total length for these ear weights are 5.5cm, they weigh approx 28g each. _____________________________________________ My tip for wearing these... lube up them lobes! Put them in head first, but put the left side in with the head facing the back of your ear, and the right side, put the head of the snake facing the front of your ear. I know this sounds complicated but it means that the snakes are both facing in towards your face and it looks really good this way!
