Soladey Ionic Toothbrush Replacement Brush Heads Refill, 4 Count -4 Row Ultra Fine Bristle Made in JAPAN - Shiken

My family has been using Soladay toothbrushes for a long time, but recently my parents don't seem to use them, so when I asked them, they said that brushes with normal hardness are hard.
Certainly, with regard to the brush that says “normal,” I thought this one was also a little stiff, but if you are an elderly parent, I understand that it feels like a stiff brush, and as a result of investigating if there are no types, it turns out that there are softer brushes, and there are also those called fine hairs, so I bought both of them.
Since I softened it, my parents began to use it, so I thought I should have looked it up sooner.

I choose this type because I have weak gums and I want to brush the gap between my teeth.
My wife also uses the same type.
I thought I would recommend it when the children grow up too.
I also used electric power, but I love this soladay for everyday use with ease of use.
I will try to change the upgraded type if the current one breaks, but I will continue to use it in the future.

The normal of the standard came to feel hard, and I changed it here.
Superfine hairs are nice to be gentle.

The bristles of this brush far exceeds the standard bristles. I love this toothbrush so much I bought another one for travel.

Perfect replacements for my Soladay ionic toothbrush.
