Review on 🌿 Environmentally Friendly Brush with Bamboo Toothbrush - 4 Pack with Plant-Based Bristles by Karla Schwinden

It was hard to find an all natural toothbrush. They are usually either plastic with natural bristles or bamboo with nylon bristles. I thought I had finally found a natural toothbrush when I came across this product. The bristles are made entirely of castor oil! What a great concept! Well, upon receipt of the product, it says very small on the packaging that the bristles are 62% castor oil, not 100%. I can only assume that the other 38% is made from petroleum products. Okay, this is an improvement over other toothbrushes, but I don't appreciate what strikes me as misleading advertising. Also, the bamboo seems to have a slightly rough surface when sliding into my mouth. And part of the brush seems a little small. I like that they try hard but don't cheat. If you can't use 100% castor oil, how about PLA?
