They have very flexible tips ("nose") which results in them easily bending while trying to remove food residues, which ultimately just pass through them and are minimally removed. Surprisingly, while they are soft, they hurt the gums.

I bought these specifically because I thought they were the right size, but I ended up buying a larger one than I needed, which made it difficult for me to clean. Also, one is not enough because they wear out very easily. In conclusion, my review is such due to the wrong size and the quick wear and tear.
