iO Ultimate Clean 교체용 브러시 헤드, 6개입, 화이트

My dentist told me to switch to these and honestly the fit is perfect on my Oral-B handle, no wobble at all. Six heads means I'm set for a year and a half, which is way better than buying singles.

The bristles are noticeably stiffer than my last batch, which took a day to get used to, but now my teeth feel professionally polished every morning. The six heads should easily last me the full year, and the snap-on fit was perfect on my existing handle.

The bristles click in securely and stay put for the full three months I push them, which is more than I can say for cheaper heads I've tried. They fit my Oral-B handle perfectly and the polish action leaves my teeth feeling noticeably smoother after each brush.
