iO Ultimate Clean 替換刷頭，6入，黑色

Finally switched from my old brushes to these and the difference in how clean my teeth feel is noticeable right away. The bristles are firm but not harsh, and they snap onto the handle securely without any wiggling. Six heads in a pack means I won’t have to think about replacing them for months.

I’ve been using these with my electric brush for two weeks now and the cleaning head locks in so snugly there’s zero wiggle, plus the bristles feel firm but gentle on my gums. Six in a pack means I’m set for months without thinking about it.

The bristles are angled just right—my gums feel noticeably less tender after a week of using these, and they fit the handle securely without any wiggle. Six heads in one pack means I'm set for nearly a year and a half, which is solid value for the price.
