Interproximal-0.7mm

Did not work for my teeth as the bristles were not sturdy enough

Have purchased this item many times the fact that I reorder should indicate my complete satisfaction. You should take note of this and STOP asking me to to rate this product thus wasting my time. I have to tell you now that I will not in future rate products that i purchase in future.

Have been using these brushes for 18 months now, they really work very well and do not break like the metal one.

Just the job, does what it says on the box
