I would save my old toothbrushes to use around the shop.
Then one day I needed to spread some gasket maker, I didn't have any old toothbrushes so I used one of my new toothbrushes.
After that I went to the dollar store and bought a bunch to use around the shop so I wouldn't waist any more of my personal toothbrushes
BTW how come you so familiar with dollar store toothbrushes?
You know the price, obviously you must buy those for yourself.
Honestly, I would use em but their too soft,
I like a Firm toothbrush and I buy those from Walgreens 3 pk
I forget the price but I wish they were 3 for $1.98
